Here is a hum-dinger of a problem that I have not found an answer for. I am using the ASP.NET ajax control toolkit controls on a few pages, which by nature want to load script resources via WebResource.axd. This is all well and good for some applications, but each call to WebResource.axd requires an HTTP request. Most pages will pull a...
I keep getting errors like this on one of my sites. It tends to happen randomly throughout the day any for periods in the night when I would not expect users on the site. It is always from different ip addresses System.Web.HttpException: Invalid viewstate. at System.Web.UI.Page.DecryptStringWithIV(String s, IVType ivType) at ...
. Hi, We are building an ASP.NET application with C#.net as language. Here, when the IIS renders a page & when we analyze the page code with YSlow tool it shows many WebResource.axd and ScriptResource.axd files (as we are referring many script files in the page). Server-side code is executing fast but loading of these .axd file...
We are referencing a .NET Ajax dll within our website. When I access a page within the site, I can see that there are different 'd' querystring parameters for the same Ajax handler when I load the page from a specific server as opposed to when making the same request through the load balancer (see below). The t parameter is hashed from...
I have created my own custom httpmodule to handle url rewriting so that urls like www.contoso.com/help/default.aspx will point to www.contoso.com/default.aspx where the actual resource is located. This works fine, but because of my implementation of an httpmodule I am having problems with ScriptResource.axd not being run properly to add...
I have an ASP.NET 4 webpage that contains an update panel which just allows me to add a few items to a drop down list without reloading the entire page. The page works fine on the Visual Studio 2010 ASP.NET Development Server, performs the Async call and the page is properly laid out. However, when I deploy the page to IIS7, the Async ...
So here's the deal. We have a Flash application that is running within an HTML file. For one page we call a legacy reporting system in ASP.NET that is within an IFRAME. This page then communicates back to the Flash application using cross-domain scripting (document.domain = "domain" is set in both pages. THIS ALL WORKS. Now the kick...
I'm using the Telerik controls form MVC and they work great in my work/home dev environments, and in the work prod environment, but when I tried to deploy to my home prod environment (IIS7) I get a problem. I've added the axd mime type, but wan't sure what else to do. I read a post suggesting adding a handler, but wasn't sure if I'm se...
Where can I learn how WebResources.axd or ScriptResources.axd actually works? What is the string that is appended to the .axd? Does this string change, or is it constant? Is it page, session specific? Can these files be cached on a proxy? How does it work internally? This is especially important after the ASP.NET vulnerability was ...

Parameter name: instance I've googled around a lot, and looked ...
Hi, I'm trying to make use of ajax control toolkit in a wss 3.0 application. It works well over http requests but over https it throws error code 500. In a https request it manages to load everything, including the scriptresources related to the ajax functionality, but not the scriptresources which is specific to the ajax control tool...
Considering the recent ASP.NET vulnerability, what should I look for in my httphandlers that would cause such a Padding Oracle vulnerability? Asked in another way... what did MSFT do wrong and what did they fix in their handlers? ...
Scenario: I have a complex Asp.net app serving various units through programmatically constructed control collections in HttpModules. Some of these controls use Asp.NET Ajax. Across many different units, ScriptResource.axd averages a transfer size of ~27k. I have a ceiling that only allows ~3k for it. There definitely isn't time to ...
