GET /jp/res/11107882.json HTTP/1.1
If-Modified-Since: Tue Jul 02 2013 08:41:51 GMT+0100 (IST)
Host: api.4chan.org
Connection: keep-alive

Why am I getting a 200 response code instead of 304 when I send this request? The headers I get back have last-modified: Mon, 01 Jul 2013 17:47:08 GMT so shouldn't it be returning a 304?

Some servers ignore it and the ones that don't interpret the header differently. I think 4chan uses Nginx or something, and Nginx in its default configuration apparently only sends 304 if the last modified dates match exactly.

All HTTP date/time stamps MUST be represented in Greenwich Mean Time (GMT), without exception.

This is another one of those stupid decisions by the w3c... HTTP/1.0 came out EIGHT YEARS after the first edition of ISO 8601, and yet it only allows an awfully verbose and difficult-to-parse date format. 1.1 didn't change that. Even an epoch like If-Modified-Since: 1372756412 would've been better (if you're going to mandate GMT, what's the point of allowing a date format that could specify a timezone?)
