I want to send css and js files from a PHP script so I want to allow caching.
But PHP always sends the following headers:
Array
(
[0] => X-Powered-By: PHP/5.2.6
[1] => Expires: Thu, 19 Nov 1981 08:52:00 GMT
[2] => Cache-Control: no-store, no-cache, must-revalidate,
post-check=0, pre-check=0
[3] => Pragma: no-cache
)
AFAIK it's not possible to remove or suppress headers but I can of
course overwrite them.
The question is: with what?
For the Expires header I suppose it could just be the RFC822 time for
now + 1 hour.
For the Cache-Control header it's less clear. Here's the spec but I'm
still trying to decipher the meaning of each directive:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9
For the Pragma header I'm largely clueless.
Does anyone know what values for these headers would be equivalent to
not specifying them at all?
