Using httpModules

Question

Our solution for SharePoint 2007 include WebConfigModification that add httpModule to web.config of all SharePoint web applications. HttpModule used for collecting information about http-requests.

I've tried to do the same for SharePoint 2010 (web.config was modified directly - without WebConfigModification). My implementation of IHttpModule, added by web.config is not loaded.

Can I use httpModules in SharePoint 2010 or modules was blocked?

Should I make additional actions to register my module, for example, add my assembly to some safe list?

Answer 1

The reason could be that your application pool in IIS7 is running in Integrated Mode.
To fix it, read this post from Rick Strahl ("HttpModule and HttpHandler sections in IIS 7 web.config files")
and also the following post http://aabs.wordpress.com/2007/11/16/ihttpmodule-not-running-after-conversion-to-iis-7-and-net-35/

Thanks for reply!

I've fixed my problem. I moved the line with module definition from section <httpModules> to section <modules> and add attribute preCondition="integratedMode".
