Disable HTTP compression on Apache servers

This article explains how to check if your Apache® server is compressing HTTP. It also
explains how to disable the compression.

Testing your server for HTTP compression

1. Connect to the server using OpenSSL.

2. Add the following request to the header to check for HTTP compression:

   Accept-Encoding:compress,gzip

If you enable compression, the server responds by compressing the page. If the server does not
support compression, it displays the page in plain text.

following steps:

1. Disable the module mod_deflate by using the following command:

   $ sudo a2dismod deflate

2. Restart the server:

   $ sudo /etc/init.d/apache2 restart
