Apache Cache Control in httpd.conf

Hi,

I've got a website that links to lot's of pdf files, these pdf files change very often. I'm trying to find out what I should put into httpd.conf so that the browser's (IE and FF) don't cache the pdf file for more than 5 minutes.

I want to be sure that this doesn't affect how any of the other file formats are cached at the moment only pdf files.

Hi,

There are 2 ways I know of to do what you need:


I
you should use the mod_expire of apache http://httpd.apache.org/docs/2.0/mod/mod_expires.html
ExpiresByType application/pdf "access plus 2 hours"


II
# browser cache expires in 2 hours
<FilesMatch "\.(pdf)$">
Header set Cache-Control "max-age=7200, must-revalidate"
</FilesMatch>
