问题
I have a strange issue, whereby when I enable output caching in Orchard CMS and have ImageResizer.net cache plugin enabled, I get duplicated page content (full DOM). Just for reference, I am deploying to Azure Small Reserved instance.
Any ideas how to resolve this - do I need to create a cache profile for output cache not to cache images as this is taken care of by the cache plugin?
Thanks in advance,
Peter

This can be reproduced without ImageResizer, using the following HttpModule:
public class BlankModule : IHttpModule {
void IHttpModule.Init(System.Web.HttpApplication context) {
//Having any event handlers registered for this event causes cache duplication during the Filter execution
context.PreSendRequestHeaders -= context_PreSendRequestHeaders;
context.PreSendRequestHeaders += context_PreSendRequestHeaders;
}
void IHttpModule.Dispose() { }
protected void context_PreSendRequestHeaders(object sender, EventArgs e) {}
}
Make sure you register it in Web.Config:
<system.webServer>
<modules>
<add name="BlankModule" type="BlankModule"/>
</modules>
</system.webServer>
Register another copy of the module, and you'll get tripled responses, not just doubled.
This is not necccessarily a bug in Orchard.Cache.Contrib; it's more likely a bug in the way ASP.NET handles PreSendRequestHeaders in combination with buffered response filters.
Unfortunately, there's no easy workaround from the ImageResizer side, as ImageResizer needs to be able to set the correct mime-type for an IIS-served file, which means PreSendRequestHeaders.

Orchard 1.7 and new OutputCache module solves this problem. You can view it here: https://orchardcache.codeplex.com/workitem/26
