To Get The Postback To Execute On This Web Farm?

Apr 6, 2010

So I have an ASP.Net web forms application that is using URL Routing. It works great on the old single server shared web hosting account. It has been moved over to a new platform that appears to be a web farm. When a postback happens it now just refreshes the page and the event handler is not envoked. Another thing I've noticed is they put the application into a sub-folder on the account and are using ISAPI Rewrite to point the domain to the sub folder.how to get the postback to execute on this web farm?

Javascript - Get Client - Side Script To Execute On Postback (from An UpdatePanel)?

Jul 15, 2010

Basically I want to get some javascript to be sent back to the client and executed from a postback inside an UpdatePanel. Furthermore this is inside of a reusable WebControl. I've tried

this.Page.ClientScript.RegisterStartupScript and this.Page.ClientScript.RegisterClientScriptBlock but Firebug shows that those scripts aren't sent back in the postback's response.

I also tried straight up writing a <script> tag inside the control's main div in the Render method, which does get sent back but isn't executed. I got a hacky solution working, but ideally looking for a cleaner solution. The hack is to add a 1x1 pixel img with width/height set to 0 and use that for an onload event to execute the script and that works, but it seems like there has to be a cleaner way to do this.

DataSource Controls :: How To Execute Object Data Source Method On Postback Only

Aug 10, 2010

When my page is first loaded i receive error message stating to the effect

cant find Email for GetInvoicesByVendor.

this refers to a function in another class file:

Public Shared Function GetInvoicesByVendor(ByVal Email As String, ByVal vendorid As Integer) _

As IEnumerable

SQL Server :: Stored Procedure - EXECUTE And EXECUTE Sp_executesql

Mar 10, 2011

I am looking through a sql stored procedure which I might need to update in the near future. Basically the stored procedure is about 20 lines long. The stored procedure first builds a query

and stores it in a variable named "@Sql". And then for the last two lines of the stored procedure it appears that the big sql statement stored in "@Sql" is executed by using the "EXEC" command. See below. What is confusing though is that the query appears to be exectuted twice? Why was the query written in this way. Don't both lines do the same thing? Why is it being done twice? Could this possibly be a mistake on the
part of the person who wrote the query. Below are the two lines I am talking about?

EXEC sp_executesql @sql
EXEC (@sql)

Can Use Web Farm And Web Garden Together

Jul 6, 2010

Web farm is used for multiple request and multiple user using switching among them.

Web Garden creates worker processes for every processor individually for one user.

Is it possible to use worker process as a switch and convert it into Web Farm that can allocate multiple processor on bases of algorithm?

C# - How To Call Particular Web Farm

Sep 29, 2010

Currently have an asp.net web site which is contained on 2 web servers which are load balanced i.e. web farm.

I would like to have some code which would allow me to call a particular server and execute a method on it. I WANT TO do this so that i can force all web servers to refresh their cache via a web page on the site.

Use Case is: Admin user logs into site and makes a change to a setting which is cached and then clicks "Refresh web server cache" button which then calls the update cache method on each of the servers. this is to prevent me from having to restart the app pool every time a cached setting is changed.

.net - Authentication With A Web Farm?

Feb 24, 2011

Given the idea of a web application (.NET 3.5+)

Browser
web app

the authentication using forms will result in a similar line of code

FormsAuthentication.SetAuthCookie(strUsrNm, True)

this is fine in a non load balanced server instance. how does authentication work in a load balanced stuation (no sticky session/infinity), and you cannot store the client IP, users password or login in the browser.

Browser
Load balancer
Web app (on server 1) || Web app (on server 2)

limitations: no database sessions, no AD server (for example: cater for external users)in short - in a load balanced situation how does the appliation know who the user is if they authenticated against the other server without re-authenticating.

.NET Page Caching In A Web Farm

Mar 11, 2010

We have a small web farm(2 servers) balanced by the built in network load balancer in Windows 2003. We have a few pages that use page caching. My question is: Is it possible that that a given user could cause a page to be cached and another user see that content? Here is the page directive for the page in question:

<%@ OutputCache Duration="1" NoStore="true" VaryByParam="none" %>

The reason the duration is set to "1" is to ensure that the page isn't cached any longer than 1 second because of transactions that actions on the page can trigger.

WCF - How To Execute Server.Execute Asynchronously

Mar 30, 2010

I need to run the HttpContext.Current.Server.Execute method in my ASP.NET application. This application has a WCF operation that does some processing. Currently, I am to do my processing correctly from within my WCF operation. However, I would like to do this asynchronously.

In an error to attempt this asynchronously, I tried running Server.Execute in the DoWork event handler of a BackgroundWorker. Unfortunately, this throws an error that says

"object reference not set to an instance of an object" The HttpContext element is not null. I checked that. It is some property nested in the HttpContext object that appears to be null. However, I have not been able to identify why this won't work. It happens as soon as I move the processing to the BackgroundWorker thread.
My question is, how can I asynchronously execute the Server.Execute method?

State Management :: How To Use HttpContext On A Web Farm

Aug 16, 2010

I'm considering using the HttpContext.Items HashTable to store reuseable user data (per user) instead of in the Session,

I'm hoping that this data is stored on the client and not on the server, but I did not see anywhere that this is the case...

Also, is there any drawback or loss of data that can happen when using web farm or clustered web servers ?

C# - WebResource.axd Throwing Exceptions In Web Farm?

Jan 17, 2011

We have an array of about 12 servers serving a website. Over the past few hours, one single server has started throwing exceptions for WebResource.axd and ScriptResource.axd requests.

Exception

System.Web.HttpException - This is an invalid script resource request.

Stack Trace

at System.Web.Handlers.ScriptResourceHandler.ProcessRequest(HttpContext context)
at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Broken server URL

/WebResource.axd?d=S6kjkBsrIKni9uO5HCkv0c8eYObzibWXn9R6A7Yr_Fy7CW4dRFZm1HfcnUTEZ8xBYZDM-5zeTVk1tTgC1hp7d5YYw3o1&t=634308186300177825

All other servers URL

/WebResource.axd?d=yj6PW1hbOvqhMkOh2gYGlw2&t=634207187366247462

I have checked the web.config, machine.config for every server and they're all identical. The only difference been able to find so far is that prior to the problem commencing, the servers were patched, after which, the problematic server looks to be using different version of the System.Web.dll to the others?

Synchronizing And Coordinating Processes On A Web Farm?

Oct 15, 2010

in my ASP.NET app happen asynchronously (i.e in background threads without any access to HttpContext). Let me take an example of one such action. The app would be deployed to a web farm soon.

The background threads would be processing files deposited to a network share location. So, when the app starts, I create a FilesystemWatcher to monitor activities on the desired network share folder.

As soon as a new file arrives, the code processes it and marks it as completed processing.

The problem is with multiple servers watching the same network share, the same file might get processed on different machines, meaning redundant results. On a single server, I use locking mechanisms to prevent race conditions.

Now how to prevent the same on a web farm?

C# - Distributed Critical Section In Web-farm?

Mar 18, 2011

I have about 50 web-sites, load-balanced across 5 web-servers. They all use Enterprise Library Caching, and access the same Caching database. The items in the Caching database are refreshed every few hours, using an ICacheItemRefreshAction implementation.I want to guarantee that only one web-site ever refreshes the cache, by putting the refresh code in a critical section. If the web-sites were running in a single app-pool on a single server, I could use a lock()If the web-sites were running in separate app-pools on a single server, I could use a Mutex.However, these will not ensure the critical section across multiple web-servers.Currently, I am creating a new key in the caching database to act as a mutex. This will generally work, but I can see a slim chance that 2 processes could enter the critical section.

public class TakeLongTimeToRefresh : ICacheItemRefreshAction
{
#region ICacheItemRefreshAction Members

Unable To Use Web Garden To Simulate Web Farm Session

Jan 13, 2011

I just stumbled across the concept of a "Web Garden" in an IIS App Pool. That is, when more than one process serves the same webpage. From what I understand, this means ASP.NET InProc sessions have the same problems as a web farm.

My question is, assuming your production environment is a web farm but your development/test environment is not, would it be to set up a "Web Garden" in dev/test? I'm thinking this would help catch any multi-process/server issues early on, or at least confirm that everything works as expected.

Security :: MembershipProvider / RoleProvider With Server Farm

Nov 16, 2010

I trying to understand how a server farm would use MembershipProvider / RoleProvider. If I have a million users, I do not want to have multiple copies of the MembershipProvider / RoleProvider database. I would like to have one set of machines used for login but then redirect users to other machines in the server farm depending applications the users decide to use. However, once they are redirected to the new machine, I do not want the user to have to relogin. I want the credentials and role information to be available.

Does anyone know how MembershipProvider / RoleProvider is configured for this type architecture?
