Squid set download limit and prevent downloads by extension







Open squid.conf file

sudo vim /etc /squid3/squid.conf

search for reply_body_max_size you can see a line like this

reply_body_max_size 10 MB it will limit the download by 10 MB.

This option specifies the maximum size of a reply body. It can be  used to prevent users from downloading very large files, such as MP3’s and movies.

To prevent download of a particular file type you can use regular expressions

acl mp3_ext url_regex -i \.mp3$

This acl is to prevent mp3 downloads.The http_acces for this acl is

http_access deny mp3_ext

To prevent youtube streaming

acl flash rep_mime_type video/x-flv

and the http_acces

http_reply_access deny flash

We can group different types and write it in a file and can be asked to block

acl denied_filetype url_regex "/etc/squid3/denied_filetype"

Now the types written in the file denied_filetype will be blocked with the below http_access

http_access deny denied_filetype
