apache tutorial - Data Compression Using the Apache Mod_Deflate Module - apache - apache web server - apache server - apache2

• Increase website performance using the apache mod_deflate module
• we can use compression tester ( compressiontest gzip ) to reduce page load times and the amount of bandwidth our site uses.
• This can be achieved via gzip compression

How to enable data compression using the mod_deflate module

• Below are the steps to enable data compression by apache config location mod_deflate module in your .htaccess file.

Using data compression with the Apache mod_deflate module:

• We can use the apache mod_deflate module to compress output from our web site that is sent to client browsers.
• Using data compression can reduce page load times and the amount of bandwidth our site uses which can be tested via gzip test
• enable gzip compression - To enable data compression with the mod_deflate module, use a text editor to edit the .htaccess file.

content encoding gzip example:

• Below code configures apache server that demonstrates one way to enable data compression by specifying file extensions (mod_deflate):

<IfModule mod_deflate.c>
    <filesMatch "\.(js|css|html|php)$">
        SetOutputFilter DEFLATE
    </filesMatch>
</IfModule>

• In this example, apache server compresses any file that has an extension of .js, .css, .html, or .php.
• Alternatively apache web server use MIME types to specify which files to compress.
• The sample configuration demonstrates as the following:

<IfModule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css text/javascript application/javascript
</IfModule>

• In this example, Apache compresses any file that uses one of the MIME types referenced by the AddOutputFilterByType directive.
• To disable data compression, we can delete the relevant lines in the .htaccess file, or comment them out by preceding each line with #.
