No, but you may have to adjust the max_object_size.

Squid uses two methods:

a) If the web server tells for how long the page will be valid then
Squid uses this as a fact.

b) If not told, then Squid applies the settings of refresh_pattern.

If a request for a object which is no longer considered fresh by the
above rules, squid querie the origin server to see if the object has
changed.
