Configuration :: Managing A .net Site Across Multiple Servers
Mar 28, 2011
A friend and I manage a large website for a company. The site is build using Visual Studio 2005 and is a series of nested web applications run inside a master application employing nested master pages. Currently we have to manually move files around folders and FTP them to various servers and I am looking for a way to be able to manage the deployment end of the site in a more automated fashion. I'd like to be able to work on my local version of a project and once I'm done be able to hit one button and publish the site to our internal testing server and then when testing is complete hit another button to deploy it to the live web servers. Right now we have to manually navigate the windows folders and copy pages, css files, images, swfs, etc and FTP them manually. The driver for this is that we have a new junior develop starting and want to remove the manual aspect in advance of him starting.
We have built an asp.net application according to 3 tier architecture, but Data Tier and Application logic lies on the same server. Our client needs that to be deployed in 2 different servers. Only front end in web server DAL & BLL in app server. Database is in different server. All 3 servers are at different physical locations. How can we commuicate between these servers and our applicaton tiers? is there any option in IIS so that we can deploy only back end code in another server? what is the best approach to communicate between different application tiers when they are physically apart?
The question: Is it possible to configure multiple SMTP servers or update the SMTP object server information at runtime?
Description of problem: The site I'm working on has a few pages which send emails. Our site is using Gmail so even though it's a custom domain our email is sent out though Gmail SMTP servers.
Some emails come from the system and some emails come from users in certain groups. I have an SMTP server configured with the admin email for the system e.g. admin@mysite.com This works fine and when I get the email it shows from admin@mysite.comOne of our user groups let's call it "groupA" has an email configured on our domain i.e. groupA@mysite.com When I send the email and specify a from address for the MailMessage object as groupA@mysite.com it still shows up in my outlook as coming from admin@mysite.com I did a little further testing and if I specify both the from address and the ReplyTo as groupA@mysite.com it will show as From=admin@mysite.com but when I choose reply in outlook it shows groupA@mysite.com My best guess is that Gmail is overwriting the From address with the SMTP user to prevent email spoofing.
I found this: http://www.systemnetmail.com/faq/4.1.aspx but it won't work for me since group A, B, and C all need to send emails from the same page.
how to structure our intranet. The way it's going right now is, that I'll create a web application that usually contains just a single web page and then deploy it. I'm using the file system deployment to deploy to a test server.
The file structure on this test server is something like "\serverwebintranetwebapplicationsAPP_NAME". I would create a folder on the server with whatever name to replace "APP_NAME" and then deploy into that folder. Everything deploys fine and is structured fine, none of the pages will load.
When try to load the page you get an error like: Could not load type 'WebInterface._Default'. The dll containing that code is definitely there. Inside the "APP_NAME" folder is the bin folder, config file, and the (usually) single aspx page. So for some reason, the web page can't find the dll files.
I have a php forum and an asp blog, and i want to host the two apps in different servers. I will install the asp blog in the root of the domain, and the php forum in a subcategory.
So, it will be like this:
http://www.domain.com - asp blog http://www.domain.com/forum/ - php forum
What is the best way to do this ? How can i do this as far as dns related stuff ? Should i install the php forum in a category, like all domains are, or in a subcategory inside it, like a domain's subcategory ?
Am i going to have problems with the forum script (or addons) because of this situation ?
I am part of a development team building a new ASP.NET 3.5 web application. Two of us are C# coders, and the other is a VB.NET coder.
I know that we can mix languages on a per-project basis, and one can build classes in one language that inherit from classes written in the other language in a different project (which we are already doing), but I can see us getting into a situation where we might well end up with cyclic dependencies between our various project DLLs.
Other than simply having a high number of projects (more seperation of concerns into more libraries), how have you managed this situation on your own projects?
Note - I believe this question to be different enough from the only similar match I could find (this one) on the basis that we are not wanting to use different languages in order to take advantage of their specific features per se, but rather to make use of what developer resource is available to us (i.e. one dev just happens to be VB.NET only).
have a question related to sitemap ........i have a pool of websites which are same in function but different in css and format ..every site in that pool different from each other in terms of information so each site in the pool would have different sitemap.xml but the problem is how would i know that the Google crawler or other search engine crawlers are picking the right sitemap ... ?is there any place where i can identify that sitemap-abc.xml belongs to abc site and sitemap-xyz.xml belongs to xyz site ? ll the xml are put in one folder only difference in between them is there names ..
I am sorry if this is been discussed earlier. I am having a problem maintaining the session when someone uses the same browser with multiple tab, the results gets messed up. A perfect example would be, [URL] if you open IE (or any other browser) and open two tabs and search for two different air travel itinerary and the results will completely overlapped (real mess). I know the cause for this problem (both tabs uses the same session). I would appreciate if somebody have any solution for this. I am using ASP.NET 3.5/VS 2008/VB.NETI will not be able to use Viewstate since I use a master page and pre-init event where view state is not available.
I am making project on hospital management which will contain different databases for different hospitals. how can i manage this thing with single asp.net project?
I'm just wondering what the best practice is for managing web.config connection strings and SMTP settings when working locally in VS2008 and deploying to a remote server?
I see a ton of questions about uploading multiple files, but none about uploading a single file to multiple servers, so here goes... I have an ASP.NET app that will be running on two load balanced servers, and I would like to allow users to upload files and have them end up on both servers. What is the cleanest way to do this? I am using IIS 6 btw. Some ideas that come to mind are:
1) Use a virtual directory that points to some shared location that both servers can access. Will there be any access issues if the application runs at Network Service? I'm assuming the application will need to run as a user account that exists on the shared location machine. How should the permissions be set for this?
2) It would be nice if I could via jQuery post the request to both of my servers, referencing them by their port numbers. Even though the servers are on the same domain, this violates the same origin policy, right? Is there another solution I'm overlooking? How do other sites do this?
If same web application is deployed on three different servers, which things we need to take care of and what things should be common amonges all three?
I have a situation where we are splitting dynamic content from static content and each is getting its own web server. The people maintaining the site want to be able to make navigation changes once and have it show on both servers without any major extra work (for them). I'm putting the navigation structure in an XML file which also has information on things specific to each content page. This brings me to the question of how to share that file. If I want the change to be instantaneous I can't rely on a scheduled task to copy the file from one server to another.Access to one of the servers is very limited due to security policy.
I am thinking about maybe a web service running on one server to get the data from it to pages on the other server. Does this sound viable or do any of you have other ideas that may work better? I considered having the navigation in a database but this introduces the need for a tool for the navigation updaters to have for them to do that. It is easy for them to update XML and just publish to the server with a lower security level. To get them database access requires terrible paperwork and meeting with security people.
I have two applications with a single domain name ([URL] and [URL]). First one has been developed in .NET 2 and the other one with .NET 4. I have configured web.config as these steps:
1- I've set the same machine key for both of them. 2- I've set the coockie name. 3- I've set the domain name to "domain.com". 4- Also, I've set hardcoded coockie domain name to "domain.com" .
Everything was working fine when both of them were running on a single web server. Recently, I've been asked to move test.domain.com to another server. After moving, authentication ticket is not valid on the second server. I tested both of them on a single server again and everything was workinh fine, but in two servers users can't acces to test.domain.com. (Authentication Ticket is invalid)
Edited: The second server is a virtual (VMWare) server. I don't have any problem in physical servers. I checked the server's time to be synchronized. I also used fiddler to see if the server does not get the auth ticket and ther ticket is sent to the 2nd server. Note: Servers are located in different networks and maybe proxy or firewall causes this (I've no idea)
How do i store same file into multiple servers? My scenario is explained below Administrator module resides in production server ( "cccc" domain) which is accessible only within my company. Common module resides in DMZ and can be accessed by internet users. I have written a program to upload a .xls file to both the servers. My program is in administrator module and resides in cccc domain. I could upload the file to the server in my company but i cant upload it in DMZ. Following is the code to upload to ccc domain
FileInput.PostedFile.SaveAs(Server.MapPath("..TU" & ServerFileName)) Followins is the code to upload to dmz FileInput.PostedFile.SaveAs("http://grtr/" & "/TU/" & ServerFileName) I will get the serverfilename using file upload control
Can multiple SSRS share the same DB? We're getting into an SSRS customization scenario, which may adversely affect our existing SSRS features, and I wanted to see if it was possible.
We have an IVR product that reads a configuration database for callflow information. I am writing a tool for our implementation team that will allow them to add/delete/update the data in the configuration database. Once the tool is in production, the implementer will use only the production release of the tool to modify the configuration database in all four of the IVR regions (Dev, QA, Cert, and Prod). Each region has its own database with identical schemas. The tool has 'tabs' across the top for each region. If a user is currently working in the Dev region and clicks the QA tab, how do I switch my connection from the Dev db server to the QA db server?
We have a web application that is storiing all site data in HttpRuntime.Cache. We now need to deploy the application across 2 load balanced web servers. This being the case, each web server will have its own cache, which is not ideal because if a user requests data from webserver1 it will be cached, but there next request might go to webserver2, and the data that their previous request cached won't be available. Is it possible to use a shared-cache provider to share the HttpRuntime.Cache between the two web servers or to replecate the cache between them, so that the same cache will be available on both web servers?
how can I synchronize sessionID over multiple second-domain servers? For example, I've got servers(you can log-in into server swarm at any of these), [URL], [URL], [URL] and if you log in at one of them, the login information (+anything else) should persist along them. How can I provide SessionID to other domains? (session itself is stored on sql server shared across the services).
We have a problem where in the user can download files from an email. A link that will redirect to a page where the code to download the file resides. Before the download the user needs to be logged in to the system for security. The problem is that sometimes for whatever reason when the user clicks the link the download dialog box does not appear and just a blank white page. It happens only on our staging environment where we have 3 servers.. We can't reproduce this in our dev and test env. where we only have one server.
I have 2 front end servers and 2 back end servers. There is a registration form in my web application. The registration form uses a Microsoft Wizard control. Lets say the Wizard control has 4 steps. After the fourth step, users click "Finish" and I display the "Thank you Message". The way the request is routed between the 2 servers is round robin. So lets say till the fourth step, the response comes from server A. After the user clicks "Finish", lets say the response now comes from server B. After they click "Finish", I am trying to access some information in the Wizard control (like Name, address and so on). Because the servers are now switched, the data is lost (at least thats what I think is happening). So all entries in the wizard control are now blank and when I try to read those values, they are null.
Boss comes in and demands that we change an existing dataload process written in .Net 2.0 to call stored procedures on two different servers rather than just one. In his mind (not a programmer) this should be a short overnight process. We have about 60 different SQL Commands that we need to change and test. Is there a simple way to do this that I can't think of? If there isn't we will use something like replication or database mirroring, which is my preference but is likely to get the cold shoulder from my boss, especially since I have never set these up before. A function that takes a SQLCommand as its argument and then iterates through as set of connections to execute the SQLCommand. Change all stored procs to call the same stored proc on a linked server.
I have a bunch of EC2 servers that are load balanced. Some of the servers are not sharing session, and users keep getting logged in and out. How can I make all the server share the one session, possibly even using a partitionresolver solution
public class PartitionResolver : System.Web.IPartitionResolver { private String[] partitions; public void Initialize() { // create the partition connection string table // web1, web2 partitions = new String[] { "192.168.1.1" }; }
public String ResolvePartition(Object key) { String oHost = System.Web.HttpContext.Current.Request.Url.Host.ToLower().Trim(); if (oHost.StartsWith("10.0.0") || oHost.Equals("localhost")) return "tcpip=127.0.0.1:42424"; String sid = (String)key; // hash the incoming session ID into // one of the available partitions Int32 partitionID = Math.Abs(sid.GetHashCode()) % partitions.Length; return ("tcpip=" + partitions[partitionID] + ":42424"); } }
So, I am the approach David Hayden posted on his blog [URL] to create a salt and hash the user's password by taking the user's raw password and the generated salt and using SHA1 to hash the value. I then store the salt and the hashed password in the database. zhe website is currently load balanced, so I was wondering if resulting hash value would be the same for both servers. Here is the snippet of code posted on David Hayden's blog:
private static string CreateSalt(int size) { //Generate a cryptographic random number. RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider(); byte[] buff = new byte[size]; rng.GetBytes(buff); // Return a Base64 string representation of the random number. return Convert.ToBase64String(buff); }
I have an website which runs nice on my development PC as well as on my local server.
But when deployed at clients server it gives error because of different datetime format at client server. I had checked it on 3 to 4 servers when the datetime format is same as my local server website runs fine. But when ever a datetime formate is different it starts giving error for datetime, whenever i try to do any transaction with date stored in datebase.
