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 RepliesI 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 :
[Code]....
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?

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 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
Can 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 have been working in a few MVC HTML Helpers. For example:
[Code]....
If account or url are null should I trhow an exception? Or render an empty string? Or render an Html comment in the view?
i'm using some components. When page render, components generate html comment tags. if i'm using this component 10 times on one page, html comments inserted 10 times.
How to remove html comment tag before render page?
way to write a comment at particular place in HTML from C#? For example, after a particular label? I can write a comment as follows:
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("<!-- " + ... " -->");
}
but this appears before the DOCTYPE. I'd like to write it at a particular place, or at least in the "body".Thinking about it, I guess I could create a comment label at the beginning of the body and write it there:
Label1.Text = "<!-- " + ... " -->";
Is there a way to make sure it is in the body if I do not have a Label already defined for the purpose.

We have an ASP.NET 2.0 WebForms app that uses MS Ajax 1.0. It's working fine on all our environments (dev, test, IE6 VMs etc.). However, at the customer site the client side validation is not happening.We're currently trying to eliminate all the various factors and along the way we asked them to get their page source and send it to us, and we found something interesting.In our environment, our page has ASP.NET javascript in CDATA blocks:
<script type="text/javascript">
//<![CDATA[
. . .
//]]>
[code]....
This may be a red herring, but I'd like to eliminate it as the cause of the validation issues. whether specific configurations/patches/versions of ASP.NET will make it do this?
