Do I still need to send the "Expires" header, or can I assume that web caches understand "Cache-Cont
- by chris_l
I want to reduce the overhead caused by HTTP headers to a minimum, so I'd like to avoid the "Expires" header, and use "Cache-Control" only - or maybe the other way around (I'm planning to send very short HTTP responses to browsers, so the answer to this question doesn't fully apply here: My headers account for a significant percentage).
AFAIK, the "Cache-Control" header was standardized in HTTP 1.1, but are there still web caches/proxies, that don't understand it?
