AFAIK, the RFC states that clients should always send the exact date

like I either remember it wrong or Google is violating the RFC there.
I looked at the HTTP protocol document it says that clients should be
aware that some servers might use an exact match and should send the
last modified date they got from last time.
However, I noticed that no bots get 304s when the file is served by
fetch.php.
I made the change on a live site to see what Google would do but the bot
didn't re-visit in the last few days. My site is on a shared web host so
I don't think I can capture the actual header data to see what's going on.
But I guess it wouldn't hurt to play along there anyway. Can you send
a git patch?
Once I figure out how to do it. But I am wondering if the date string
sent in the IF-MODIFIED-SINCE header needs to be sanitized before being
passed into strtotime()? I don't know enough about PHP to find out.
