View 2 RepliesI have a doubt regarding secure cookie.
I have four servers 2 App Server(behind firewall) and 2 webservers and each server is accessing through Load Balancer.
App Server is a modules for Data Access layer and webserver is for Presentation layer.
My Issue is My Load Balancer has Secure certificate installed but certificate is not installed on servers and I want to make cookie as secure in site , as per my understanding " cookie should be set as secure only for SSL site other ways new session will get create every time" so should I install SSL certificate on webserver to make my cookie as secure or will it work properly even if only Load Balance has SSL.
I have a couple of servers and a load balancer. I want to show a server name which is currently serving the page.
I am using HttpContext.Current.Request.ServerVariables["SERVER_NAME"] and HttpContext.Current.Request.ServerVariables["LOCAL_ADDR"] but is shows the same data for all servers (load balancer information is shown but not the information about exact server name).
How to get a relevant information?
I'm creating web application behind load balancer. To this moment I configured it to store session in database but I'm not sure how should I handle session expiration. The problem is not sessions are not removed from database but Session_End event because I have to call some web service method in it.
Assuming Session_End is called when expires the thing I'm afraid of is situation when session is created on one server but finished on another. In this case I'm afraid Session_End on first server will be executed prematurely and I will call web service too early. What would you suggest in this situation?
Edit:
I remember some time ago reading about Sql Agent reacting to session end event and then performing custom code. Can anybody confirm that this solution is possible?
We are using Two servers for our application managed by a load balancer. One of which server contains Windows server 2003 & other one contains Windows server 2008. When a request is served by windows 2003 server and its subsequent goes to the other one (2008 server). Users gets log out. Are we need same Operating systems on both systems because( when request served by 2008, and subsequent on 2003 is served without any issue).
View 1 RepliesI have published a website and installed it on my local machine and it works fine, but when i install it on the both servers who controlled from the load balancer i got an error like the WebResource.axd not found. how can i resolve this problem? i have checked the IIS for axd mapping, the "Check that file exists" is unchecked for both servers.
View 2 RepliesWe host a SaaS application on 4 windows 2008 servers loadbalancer via a LVS. We use infragistics and Ajax Control Toolkit on several pages, one page represents a list of people using a Web Datagrid, each time a person is clicked in the list, an Ultra Web Tab component is updated at the botom of the page with detailed information on that person. After a certain amount of clics on different people (number of clics can be between 1 and 5) Scriptresource.axd craches with the following error :

I don't get this error when I run my application on one server using the server's private IP adress. I tried to synchronize the dates of the dlls System.Web and System.Web.Extensions on each server, I still get the same error.
I haven't deployed behind a load balancer before. My customer has a WCF service built and tested on servers using a service model configuration that is relatively straightforward. It provides a service to return an image of a map for another application. To get the map, it calls other services.
The service was built in Visual Studio 2010 targeting the 3.5 framework. The customer is using IIS 7.5 and an F5 load balancer. When moving to the production server, the Web.config was changed to add the load balancer behavior and specify the endpoint to show the physical and logical address of the service:
[Code].....
There was a problem when the service was deployed to a server behind the load balancer. When I try to call the service from WCFStorm or WebServiceStudio I get the message "The provided URI scheme 'https' is invalid; expected 'http'.
The endpoints for the service itself look right to me. However in the development and testing versions of the config, the client section uses http instead of http, while on the production servers it uses the load balancer's https address. This seems like it should be obvious, but we're missing it.
Our server operations team has asked the web development team (ASP.NET) to provide a URL in our application, which the load balancer can ping to perform health checks.
What should be executed on this page? I think we should attempt a database connection to ensure connectivity between the web and database.
One issue with ASP.NET apps is that they periodically reload themselves, causing a long delay and possibly timeout for users who hit the site during that time.
This may not be a problem for small websites, but it can represent significant downtime for high-traffic sites, if users happen to get routed to node in the web farm that is restarting.
Can load balancers somehow "know" if an ASP.NET application domain on a specific server is restarting? Then, they can route traffic around this server until the application has completed restarting.
Currently, I have my load balancer ping a simple .aspx page on the site. If there is a delay or the page fails to load, the host is taken out of rotation. Is it possible to do a more targeted health check, perhaps at the IIS level rather than ASP.NET level?
I have the following web farm setup in production server. Browser --> HTTPS --> Load Balancer --> HTTP --> webserver node F5 Load balancer handles off box SSL termination. It implies that SSL resides on F5 load balancer. Problem Statement: Ajax calls do not go through unless "Access data sources across domains" option is enabled in IE security settings.
I have the similar setup in staging server except F5 Load balancer. The ASP.Net application makes perfect AJAX calls on both HTTP and HTTPS. However, the staging server web farm use windows NLB and SSL resides on individual web server nodes
I have 3 servers where 1 of them serves as a load balancing server. In my ASPX page, I want to add a HTML comment to show the IP address or even host name of the server selected by the load balancer. I tried looking through IIS Server variables and tried using SERVER_NAME but that just returns the domain URL.
View 2 RepliesCan somebody explain what ASPXAuth cookie does?
My website uses forms auth and I am trying to create a load balancer (hardware) rule which will keep track of sessions based on the aspxauth cookie. Is it safe assume that the value of the cookie is unique?
I am looking for a way to integrate a web application with a client application that will sit on the users desktop. Our scenario looks like this user will click a link in the client server application that will launch an .ASPX and pass various parameters via a querystring. User will make form inputs on ASPX page and on that input, I need to be able to execute a .EXE on the client machine that will refresh the window in the client server application.
I have looked at some tutorials for using ActiveX for this, but they all seem out of date and the ones that I have been able run prompt the user with the Activex warning dialog, which I would like to avoid.
This bug is very difficult to troubleshoot. I run 4 apps on the same server, all 4 are clones from the first one, just differ on their database connection. 2 run perfectly, but on two of them, when making a postback from a certain page, by clicking a button or by changing a datagrid page, it throws this error:

I am working on a website where when the user logs in, I select their database based on their username. Currently I have a list of all databases in the web.config and I select the Database ID from the username and then read the database string from web.config. What is the most optimal way to implement this scenario?
currently I:
- store the Database ID in the session object
- the Session object expires after like 5 minutes so i have to read the Database ID from the online database based on the username and regenerate the Session["DatabaseID"] again.
- there are some security issues with the Session ID, so I started clearing the Session in !(Page.IsPostBack) and I generate the Database string again.
Where shall I store the DatabaseID and the database connection string so I can easily reuse it once the user has logged in?
I've created 2 multi dimensional arrays (2 dimensions each), I want to feed them both into a function, and I would like the function to spit out an array or list containing both of them as arrays, so I can use them as they were before they went into the function.
The way I've done it at the moment is probably very inifficient and I'm having trouble accessing it properly.
What follows is my attempt to put the 2 arrays (attackerarmy and defenderarmy) into a new array called armyresults and adding an additional dimension to tell me if the record belongs to the attacker or defender:
[Code]....
Since I've already got the 2 arrays I want in the function, I've rather not inefficiently force them into a new array, only to try to re build them again when they come out of the function.
how to out 2 arrays of unknown size into an array of arrays for the return statement of my function, and then how I can access those individual arrays so I can easily copy them back out into their original form?
I need to make a webservice in .net (I know how this works) but then I need to get data out of a database. But my company wants to make it in a way that you can use the system with multiple databases.
So my option was make multiple abstract classes which contains the folowing code (depending on the database type, this would be a SQL database)
public abstract class AbstractDAO<T, Tid>
I'm developing a web application in asp.net using C# and need to access the command prompt of the server computer.
After accessing it I need to run a "ABC.bat" file in the server computer which is in folder "E:Test".
The absolute path of the server is "\MyServer"
PS: I need to run the ABC.bat file on the server machine as the bat file runs couple of more applications which are licensed to that server machine.
I want to create an asp.net based website. When I create the sit eon my local machine I am uploading pdf files to my file system then accessing the files to view in my website. When I make the site go live how do I translatye this? Can I have files saved somehow with my interenet host? How would I access the files though the internet host on my application?

I have been trying to fix this issue for several hours now, and I was hoping to find out if someone can shed some more light on it. I get the above error on ONLY ONE virtual root in my IIS 5.1 installation. I have other web sites I am developing in .NET 2.0 and 3.5 and they seem to work fine. This is a development workstation with only 1 user, and I get this error continuallyevery time I access only 1 of my web sites - even after rebooting the machine. It makes no difference what order I access the web sites in - this one always fails and the other ones always succeed.
Note that the web site does not use frames and the changes I made to it yesterday (just adding some javascript and a few span elements to support BuySafe's new 3-in-1 guarantee program) were very minor.OS: Windows XP/IIS 5.1Dev Environment: Visual Studio 2005/.NET 2.0Browser IIS 7.0Every page on the internet I have read about this seems to indicate it must be something with the "HTTP Keep Alive" setting. I disabled this setting but it made no difference at all.I keep full backups of my machine and I restored my OS/IIS partition from a few days ago (including the full IIS metabase), but I still continue to get the same error.The error suddenly started occuring today - I just made some updates on the web site and deployed them to production yesterday (and neither my test or production servers are exhibiting this behavior). It happened after a power failure and my UPS software forced my Lenovo T500 laptop to sleep. When the power failure occurred, both VS 2005 and a browser with this web site were open on the machine. The machine woke up and the programs were all still running, but I was no longer to access this web site.I had a problem like this years ago and I ended up rebuilding the machine from scratch.

How do I do this? What configuration changes should I make to IIS?
After publishing the web application on the web host there si following error.It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
