C# - Direct JavaScript/css Requests To Same Server As Page In Load Balanced Environment
Jan 28, 2011
I have a .net web application in a load balanced environment over 3 servers. The load balancing is done with a load balancer. My site is [URL]with serveral javascript files such as [URL]
Is it possible to set it up that when request goes to server1 for [URL] then all javascript, css requests also go to server1, server2 or server3? Is there any web.config configuration that can be put in place to handle this?
It used to work when my ASP.NET site was only hosted on a single server. However once we got the load balancer installed and migrated our apps to a web farm, the code above returns the IP of the Load Balancer device and not of the client anymore.
I am working with the networking folks to determine what can be configured differently with the load balancer, but in the meantime I was wondering if there was another way I could get the client's IP other than using that IIS Server Variable?
I have an application which works well on a single server. My customer now wants to move it to a load-balanced environment. Which things are likely to bite me when doing this?Currently I know ofSession state, andMachine key.Both of these are described here, for example, so I'm looking for things additional to this.These similar questions, but the first addresses load balancing in general, and I'm looking for a migration guide, and the second addresses a specific problem.
How can I achieve in an ASP.NET application, that a set of URLs/ASPX pages (parts of the application) cannot be called directly from the user in the Browser? These urls/pages may only be referenced in the application itself.
We have 2 asp.net web servers working through the LoadBalancer that are accessible externally. Earlier, for all applications we did logging into DB. Now we have 1 more app that doesn't work with DB, it is used for 'messages transferring'. On TEST environment it does logging into files into a local folder.
If we deploy it "as is" to PROD we will have 2 separate log files... that is not very good idea. Connecting to DB just for logging doesn't seem reasonable too...
Possible solution could be store log file into a shared folder somewhere on another server.
After a user logs off from our web-site we need to fire off some HTTP requests to 2-3 other external urls (we don't need a response from these btw).
The url request must be performed on the client as the requests will cause a log-off to be performed on these external sites on the users current session.
The only way I thought that this could be achieved would be to render some invisible iframes and set the url to each of them so that when the page loads the requests will be executed.
Is there another way this could be achieved? The above solution seems a bit hacky.
Created a new virtual directory on my web sit in IIS 6.. set proper settings and wild card extensions... published via file system from dev environment to the server but i get a page cannot be found 404 error when browsing the site...
In my development environment, my CSS loads perfectly. But when I publish the files to the server, the CSS no longer loads.
Originally, when I had this problem, it was because I was denying access to unknown users for all directories. It was also occurring in both environments.
When I fixed that, the CSS started working just fine. But when I publish it to the server, it no longer works.
The website appears to function. I can log in, navigate pages and everything. It's just that the CSS doesn't work.
I checked the permission on the directory and it has access to NETWORK SERVICE, the admin account and IIS_IUSRS.
I am new to asp.net, I have been tasked to upgrade the physical architecture to load balancing environment to support the application. I done some reading the session state should be configure to Out-Process instead of In-Proc to support load balancing. Is there any other issues I need to take note for asp.net web application to run in the load balanced environment?
I want to configure ASP.NET Website Project using WCF Service[NetTcp] (both in c#) for web-farm (for website) and NLB Load balancing (for service). I would like to configure following options for same.
NetTcpBinding.maxConcurrentCalls, NetTcpBinding.ListenBacklog and NetTcpBinding.MaxConnections
Note: During single machine configuration when I changed value of NetTcpBinding.ListenBacklog and NetTcpBinding.MaxConnections in WCF Service project to more that 10, which is default value. I got exception. When I changed this value in Website it was working fine. Due to this I had to keep in default configuration. Not sure why this is the case. Following reference gives idea how to configure in given environment but does not tell how to go about it. Ref: [URL] Update: Let me simplify a bit. Lets say I have following configuration.
2 IIS servers in Web Farm. 3 WCF Service Servers (NetTcp) in NLB Default config. for single instance. NetTcpBinding.ListenBacklog: 10 NetTcpBinding.MaxConnections: 10 NetTcpBinding.maxConcurrentCalls: 16
Now what will be my configuration setting in this environment. Will it be same as above or will be as follows.

I want to call a javascript method during page load. I am using application.master of the sharepoint server 2007 as the master page . In the content page i want to call a custom method named OnLoadFun() during loading the content page. I have written the function inside script tag in the PlaceHolderAdditionalPageHead id section of the content page.
[Code]....
How do i call the OnLoadFun method so the i is being called onload time. i tried putting window.onload=OnLoadFun surrounded by script tag within the PlaceHolderMain content section.
I want to run the LoadArray() function initialy when the page loads. This function is calling a pagemethod given in aspx.vb code file..
Partial Class test3 Inherits System.Web.UI.Page <System.Web.Services.WebMethod()> Public Shared Function Load_Array() As String() Dim Model_Name_old As String()() Dim mod_code As String() Dim mod_name As String() Dim cod_upper As Integer //calling webservice that retunrs a jagged array Dim ins As New localhost_insert_model.dbModel Model_Name_old = ins.get_Model_Name("A") mod_code = Model_Name_old(0) mod_name = Model_Name_old(1) Return mod_name End Function End Class
So how can i load the javascrip LoadArray() function onPageLoad in this scenario?
i have a requirement to show javascript Ok/Cancel option on page load. So, when the user is redirected from the previous page to this page, based on some logic in the query string, we have to display javascript OK/Cancel (page is not yet rendered here). Once the user clicks, we have to load different type of data (server side execution) based on OK/Cancel. what is the best way of accomplishing this task?
i have aspx pages with vb.net in the back. I need to use javascript to open a new window on page load. I am also sending a querystring (www.mysite.com/default.aspx?dest=register.aspx) from the previous page. I need the javascript to parse the querystring and open the new window only if the URL has a querystring.
I am trying to put in scripts for google analytics in my code. But I want it to run only if the environment is production and not in dev or qa. This javascript runs at page load itself and I am confused how to make it run conditionally. My app is an asp.net app.
Javascript is always confusing to me. There are many other javascripts in the page and I just need to disable this one. Had it been a .net code/function I would check for the environment and conditionally run the function. But I am confused about how to accomplish this type of functionality with javascript
I have created javascript function as mentioned below to hide/show some control. I am calling this script on dropdown on 'onchange' method. In dropdown first item is "-- Select --". I want to execute it on Page Load function, so by default it will be hidden. I tried to call like this on Page load, but it is not working.
how to redirect to particular page after login. I have login,EDetails,home page..
1.If the user login very first time(suppose he does not have any personal details) he should be directed to EDetails.aspx
2.User who submitted the personal details already should be redirected home.aspx page.
I have 2 tables later i will add more,1.login table,2.employee detailed table.I am using Login control for login page
I am using Version ASP.Net3.5 with MySql database, Code where i am redirecting in login page
Protected Sub Login1_Authenticate(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.AuthenticateEventArgs) Handles Login1.Authenticate If YourValidationFunction(Login1.UserName, Login1.Password) Then Login1.Visible = False Session("UserName") = Login1.UserName Response.Redirect("EDetails.aspx", True) Else e.Authenticated = False End If End Sub
I'm not sure if this is the best category for this one... Might be more appropriate in the navigation section.I am curious as to the standard for redirecting users to a entry page on first accessing a website. In my case, I am working on an adults only website that requires a warning for users that the content is only appropriate for users over 18yo, as well as containing the scripts to activate several different monitor systems to prevent children from accessing the site.
I know I can use session_start to redirect and check for a cookie... but that seems heavy. Is there a better way? Something in IIS or... something I have not thought of yet?
I'm building this small control. It should detect client resolution and set height and width values within two separated HtmlInputHidden controls. But tester property is not getting values froms this control.
[ToolboxData("<{0}:UIControlResolution runat=server></{0}:UIControlResolution>")] public class UIControlResolution : Control { HtmlInputHidden _txtwidth = new HtmlInputHidden(); HtmlInputHidden _txtheight = new HtmlInputHidden();
