I wanted to add "If-Modified-Since" support in my web server..
Based on the following URL
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
A 304 (not modified) response will be returned without any message-body.
I do that, however, I cleared my IE7 cache, closed the browser, reopened,
went to my website, and IE is sending me the "If-Modified-Since". I
respond with a 304 and don't send any data past the header. Here is the
problem, IE doesn't have the cache anymore, so it displays nothing. Why
after I've gone into IE7 and did a DELETE ALL, it still retains the
"If-Modified-Since" somewhere, thinking it has the cache?
