RadCaptcha image breaks after adding a custom HttpModule

[Augusto]

Hi all,

I'm facing a wierd issue with RadCaptcha, it was working perfectly until I decided to add custom HttpModule to the web application. (image doesn't show up).
If I remove the custom module from web.config RadCaptcha starts to work again.

<modules runAllManagedModulesForAllRequests="true">
      <add name="MyModule" type="MyModule" />
</modules>

RadCaptcha doesn't work with the custom HttpModule either on the local dev machine or in production (Azure).

I checked few forum posts and gave a try to set the ImageStorageLocation property of RadCaptcha to Session:

<httpHandlers>
<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResourceSession, Telerik.Web.UI" verb="*" validate="false" />
</httpHandlers>

<handlers>
<add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResourceSession, Telerik.Web.UI" />
</handlers>

Even tho I'm not running in a web farm or web garden, but this doesn't solve the issue.

Any ideas why this is happening?

Note: using Telerik version: 2014.1.403.45

Thanks for the help!

Hi Augusto,

The RadCaptcha control loads its image via an HttpHandler, so my guess is that the custom HttpModule you add is changing something in the request for this handler that is leading to the problem at hand. Nevertheless, I cannot determine why this happens without examining the custom module you created.

Could you please isolate the problematic scenario in a simple, fully runnable project so that I can inspect it locally and pinpoint the exact cause for the issue?

You were right I found the problem in the custom HttpModule (URL rewriting).
I have since switched to ASP.NET FriendlyUrls and things work without any problem (and much easier too).
Thanks!
