Compression and new IIS7 Migration

[Simon]

Hey Guys,

We're just porting over to IIS7 from 6 and having problems with our postbacks.  Client fires but no server-side response just reloads the page - not even the click handler executes its code. Seems intermittent, but the following error is common:

[NullReferenceException: Object reference not set to an instance of an object.]
   System.Object.GetType() +0
   Telerik.Web.UI.RadCompression.Compress(HttpApplication application) +820
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +80
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +171

Now when I remove RadCompression entries from web.config it all springs back to life, with no problems.

So I'm doing something wrong with IIS7.  I have the Registration code in both System.Web\HttpModules and system.webserver\modules.

Any ideas?
thanks

Hello Simon,

I suspect that the problem is caused by a breaking change in .NET 4.0 described here. To workaround it one can set preCondition="managedHandler" for the RadCompression module. You will also need to remove the runAllManagedModulesForAllRequests setting from your web.config if you have it (or set it to false).

I hope this helps.

All the best,
Martin

Martin - I have made all the suggested changes the I have seen regarding this error. This happens when I publish from Dev to Production, 32bit to 64bit. I did the following in the modules section of the web.config.
-    Removed  the runAllManagedModulesForAllRequests
-    Added the preCondition="managedHandler"

After the changes above I still receive the error.

Telerik version: v.2012.3.1016.40 Dev

Error:

NullReferenceException

Hello John,

I am afraid that the provided information is not sufficient in order to replicate the issue in my side. I would suggest that you open a formal support ticket and send a stripped runnable project that replicates the issue. Please also specify the server settings (IIS version and mode, app pool etc) and .NET version you use. The exact steps that I need to perform to replicate the problem would also be quite helpful.

Greetings,

Hi Everyone,

I am facing exactly the same problem, we have migrated from IIS 6 classic mode to IIS 7.0 Integrated mode. When I run the application login page shows up but as soon as we enter credentials and hit submit we get error page. when we checked event viewer logs we found following error.

We are using RadCompression in our application which was working absolutely fine on IIS 7 classic mode but the moment we moved to Integrated mode application has stopped working. Also this happens when we move from dev to UAT or production enviornment and is is working fine on dev and local enviornment.

 

.Net framework Version : 4.5.1

IIS : 7.0

Managed pipeline mode : Integrated.

UAT Machine : 32 bit machine.

Local Machine : 64 bit machine.

Hello Atif,

Please check out the following article that describes the configuration in web.config for integrated mode. Try to use similar settings and see how the behavior changes.
