[users@httpd] What expire value I should set?

[howard chen <ho...@gmail.com>]

Hello,

Consider currently I am using mod_expire to set a HTML file to 15
minutes expire.

The file change quite frequently, sometime maybe changed within 15
minutes so I want my user to see the change as soon as possible...
sometimes the file does not change even for 10 days!

So what expire value I should set?

Thanks.

Well, in that case set it to expire right away, or forbid caching.
The worst that could happen is that user's browsers would reload it each 
time.  You have to know what's worse : having someone inadvertently 
re-use a version that was replaced 2 minutes ago, or having the page 
served again by your server even unnecessarily.
