Can I prevent users from downloading large files?
You can set the global reply_body_max_size parameter. This option controls the largest HTTP message body that will be sent to a cache client for one request. If the HTTP response coming from the server has a Content-length header, then Squid compares the content-length value to the reply_body_max_size value. If the content-length is larger, the server connection is closed and the user receives an error message from Squid. Some responses don’t have Content-length headers. In this case, Squid counts how many bytes are written to the client. Once the limit is reached, the client’s connection is simply closed. Note that “creative” user-agents will still be able to download really large files through the cache using HTTP/1.1 range requests.
