TAG NAME reply_body_max_size

Description This option specifies the maximum size of a reply body
Build Option
 Default
Usage
 reply_body_max_size size [acl acl...]
Default
 none
Synopsis
Using this you can prevent users from downloading very large files, such as MP3′s and movies.

Note: 1. Downstream caches probably can not detect a partial reply if there is no content-length header, so they will cache partial responses and give them out as hits.  You should NOT use this option if you have downstream caches.
2. A maximum size smaller than the size of Squid’s error messages will cause an infinite loop and crash Squid. Ensure that the smallest non-zero value you use is greater that the maximum header size plus the size of your largest error page.
