I have upgraded a site to IIS integrated mode and now none of my plain vanilla 301 Redirect pages (using Response.Redirect) are working...
The error given is:
Specified argument was out of the range of valid values. Parameter name: offset
Stack trace shows this is being called from the .Flush() method on one of my pre-existing handlers. The handler works totally fine on other pages just not when a Response.Redirect is called from inline code.
Is there a simple way I can recover this situation? I have some sites where there are 80+ redirect pages (CMS controlled)
Thanks
