Rewriting headers

Hi Cheeso

I'm writing an HTTP handler to manage caching of items on browsers and proxy servers.

The idea is to parse the "If-Modified-Since" header in the request and compare it to the last updated datetime of the file.  I'll server file or a 302 accordingly.

However, according to this , IIS strips this item from the headers.

The workaround they suggest seems like a good idea but I don't seem to be able to successfully add any headers to the request using IIRF.

Can you help?
