Question

Browsers, do they treat a random query string as a different file?

Answer 1

+2 A:

Yes, and its a common way to work around cache control. If you use it the other way around that is.

Thanks for your super quick answer, but what do you mean by other way around?

I think he means `/css/mycssfile.css?version=1234` where the `version` argument is just there to defeat cache (it's not used at all)...

Answer 2

A:

Yes this will change it, but why not just send the http-header Cache-Control?

I'd prefer not to modify the apache configuration, at the same time I'm not in a position where I can use `.htaccess`

ILMV 2010-08-26 13:31:05

Because not all browsers or proxies respect the `Cache-Control` headers. (At least that has been my experience with temporal data written to flat xml files)...

@ILMV you're using php. http://ca2.php.net/manual/en/function.header.php@ircmaxell That's for http/1.0 (1996).
