I just noticed something bothersome. Mozilla 2.0 sends a non-standard
If-Modified-Since:
If-Modified-Since: Tuesday, 24-Jan-95 00:24:37 GMT; length=116
While I can see the desirability of sending the length, it's too bad
Netscape never brought this to http-wg for standardization.
BTW, v11-spec-05 has If-Modified-Since and If-Match out of alphabetical
order.
