HowTo Block Internet Explorer Browser With Squid Proxy Server on a Linux/Unix Server

To block the Internet Explorer browser with a Squid proxy server on a Linux or Unix server, you can use the acl and http_access directives in the Squid configuration file.

Here's an example of how to block the Internet Explorer browser with Squid:

1. Create an acl (access control list) for the Internet Explorer browser:

acl internet_explorer browser IE

This acl specifies that the Internet Explorer browser will be identified by the IE string in the HTTP user agent header.

2. Use the http_access directive to block access to the Internet Explorer browser:

http_access deny internet_explorer

This directive will block access to the Internet Explorer browser.

3. Save the Squid configuration file and reload the Squid server to apply the changes:

squid -k reconfigure

This will apply the changes to the Squid configuration and block access to the Internet Explorer browser.
