C# - What Else Can Cause 'Padding Is Invalid And Cannot Be Removed" Exception With WebResource.axd
May 7, 2010
Recently, a couple of my applications have started throwing exceptions with the message Padding is invalid and cannot be removed intermitently
My applications already have a machineKey specified in the web.config as suggested in this thread
The applications are deployed to a single Windows 2003 server running IIS6.

We're getting this InternalSubStringWithChecks exception with our application's healthMonitoring. This exception is like the Padding is invalid and cannot be removed exception where it's being recorded and we're getting a notification email but the end user is unaware that an actual error has happened. Though we don't want our event log filled up with this rubbish! The stack trace is:
Parameter name: length

i googled and read to add machineKey in my web.config <system.web> which i did:

We (out IT partner really) recently changed some DNS for a web farmed site we have so that the two production server have round-robin DNS switching between the two. Prior to this switch we didn't really have problems with WebResource.axd files. Since the switch, when we hit the live public URL, we get an error:
CryptographicException
Padding is invalid and cannot be removed.
When we hit the specific servers themselves, they load fine. I've researched the issue and it seems since they're sharing assets between two servers, we need to have a consistent machineKey in the web.config for each server so they can encrypt and decrypt consistently between the two. My questions are:
Can I generate a machineKey via a tool on the server, or do I need to write code to do this?
Do I just need to add the machineKey to the web.config on each server or do you think I'll need to do anything else to make the two server work together? (Both web.config's currently do not have a machineKey)

We have a cookie management library that writes a cookie containing some sensitive information, encrypted with Rijndael. The cookie encrypts and decrypts fine in unit tests (using Moq), works fine for MVC web applications, but when called from an ASP.net 2.0 website, the cookie cannot be decrypted. "Padding is invalid and cannot be removed."
We are sure that the cookie value is valid because we tested it 10,000 times with random data in a unit test. There is something about what ASP.NET 2.0 does when it reads and writes the cookie that causes trouble.

I have introduced site wide exception handling on my site to catch unexpected errors. The event handler sends a message to me when such an exception occurs. But the problem is that any clicks on my site will cause an exception to be thrown with the message: "This is an invalid webresource request."
I googled for an answer and only found a couple of references to 1. setting a fixed machinekey (which for some reason didn't work for me, I got an error saying that the virtual directory wasn't set in IIS, and as far as I know I'm not using IIS at all, I'm using the local development environment and then deploy to a web host) or 2. using a robots.txt file to stop robots from accessing the axd files, but that doesn't help either because it's not robots that cause the problem, anyone clicking around on the page will cause this error. how to solve this problem properly? For now I have handled it by catching and ignoring this particular error by the text in the error message, which works but I would rather fix it so that this error doesn't occur at all.

I have defined this in the web.config of a subdirectory
<namespaces>
<remove namespace="App"/>
<add namespace="Tom"/>
</namespaces>
App is imported in the parent web.config file, Tom and App have classes with the same names.To avoid errors resulting from ambiguous class names I removed the App namespace from the sub-directory where the Tom namespace is used.
However the namespace App is still imported on content pages that have a master page outside the Tom directory. This causes the aforementioned errors.Here is my dir structure
-Root Directory
--Default.master
--web.config (App is added in web.config)
--Tom Sub-diretory
---web.config (App is removed in web.config)
---Content page that uses Default.master (Here is the problem)
---Page without master (Works OK)

My web application some times gives error 'The handle is invalid. (Exception from HRESULT: 0x80070006 (E_HANDLE))' on server. I never comes on production server. Then I just upload the bin folder again on server and it starts running fine. I don't know what is the actual reason behind this.
Some experts suggested Min pool size =1, I applied that but no luck.

I don't know how strong the support of RadControls over here is, but it can't be worse than Telerik(there I'm lucky to get a response in 2-3 days), so I'm going to try here first.
Basically, I'm trying to do custom theming(using just CSS classes) throughout my application, so I tried setting the CSS classes needed on the telerik RadTab controls.
Well, when inspecting it in firebug, it adds an extra like 50 px of padding to each tab, which there seems to be no control over. This is their rendered markup
<li class="rtsLI rtsFirst">
<a href="#" class="rtsLink ui-state-default"> <!--This is the only place where I can put in my own custom CSS class-->
<span class="rtsOut">
<span class="rtsIn">
<span class="rtsTxt">
Common Application
</span>
</span>
</span>
</a>
</li>
Now, I know you can't see the style classes, but according to Firebug, every class prefixed with "rts" has the line padding-left: 9px in the style sheet which would of course explain the extra padding problem. (Why do they need all this nesting anyway?!)

ASP.NET automatically includes the following script tag:
<script src="/WebResource.axd?d=8H_C0aee9xE8e9a-3YoRhA2&t=633413907763620168" type="text/javascript"></script>
However the clients site is being proxied through another site. So the URL to the root of their site is:
http://domain.com/somename/
So I need to prefix the WebResource.axd with /somename so the resulting tag will look like this:
<script src="/somename/WebResource.axd?d=8H_C0aee9xE8e9a-3YoRhA2&t=633413907763620168" type="text/javascript"></script>
What I am not sure is how to actually set this? Is there a web.config setting I can set so it has this prefix?

I am generating a System.Drawing.Bitmap on the fly in an ASP.NET Custom Web Server Control, and then I want to serve this bitmap as part of the WebResource, because I do not want to save it on the hosting computer. Is there a way to instruct ASP.NET to serve the generated System.Drawing.Bitmap as part of it's WebResource? (therefore making it an "Embedded Resource")

I have developed some ASP.NET server controls which include their own javascript and css files. A lot of these controls use jQuery extensions which, as you know, often include their own css files.
I'm using Telerik's RadScript manager which combines the javascript like a boss. However, I'm using the AjaxToolkit's ClientCssResource attribute to include the css files in my server controls, and I have noticed that the CSS files are not getting combined at all. My pages have 10-15 WebResource.axd requests for css files for my server controls.
Everything I find only is about combining javascript, and nothing tells me how I can combine the CSS files. Does anyone know if there is a way to combine the CSS dynamically (I don't want to manually combine as each page might use a different subset of the server controls)?

My web application [URL] is currently requesting the WebResource.axd file like this:
<script src="/WebResource.axd?d=xxx" type="text/javascript"></script>
As we're using urlrewiting in a Netscaler to forward all requests for the "/social" folder onto a seperate server farm containing this app, the "/" root path won't resolve correctly as it will be requesting the resource from the something.com app.
Therefore I need to change the url of the requested script to either request it explicitly:
<script src="/social/WebResource.axd?d=xxx" type="text/javascript"></script>
or to request it using a relative path:
<script src="WebResource.axd?d=xxx" type="text/javascript"></script>
So far I've looked at overriding the render method, using a control adapter and various other things but haven't really got anywhere as of yet.
