I’ve read all the caching documentation for HTTP, and this are the headers for my file:
Edit: I am now using amazon S3 to see if it helps and still the same problem! Here go the request and the response> What am I missing? Even thought the response asks for the browser to cache the file, it doesn’t! I’ve checked the Google Chrome cache and the file is not there.
Request URL:https://s3-sa-east-1.amazonaws.com/combo-combat-release/WebPlayer.unity3d

But the browser doesn’t cache the file. Each time, the request is sent and all the data transferred from scratch (200 OK instead of 304). 🙁
File size is 37.4 MB
Any tip on what could be wrong?
Thanks,
Manuel
Try HTTP 1.1 instead of 1.0.
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html states:
Note that HTTP/1.0 caches might not implement Cache-Control and
might only implement Pragma: no-cache
