How to enable GZip compression in XAMPP server

Question

You do compression by setting appropriate directive in apache.

It goes uncommenting the following lines in your apache conf file: C:\xampp\apache\conf\httpd.conf

if your xampp installation folder is C:\xampp.

and these are the lines to be uncommented first:

LoadModule headers_module modules/mod_deflate.so
LoadModule filter_module modules/mod_filter.so

that is to say, if they have # before them, you should remove them!

Then put this at the end of your httpd.conf file:

SetOutputFilter DEFLATE 

<Directory "C:/your-server-root/manual">  #any path to which you wish to apply gzip compression to!
    <IfModule mod_deflate.c>
        AddOutputFilterByType DEFLATE text/html  # or any file type you wish
    </IfModule>
</Directory> 

Everything what is said above does not work on my XAMPP version 1.8.1 (php 5.4.7).

The only thing that works is to put on "On" instead of "Off" these line of the php.ini file:

zlib.output_compression = On

Find apache\conf\httpd.conf

uncomment the following line(remove #)

LoadModule headers_module modules/mod_deflate.so

some versions may require you to comment out the following lines instead.

LoadModule headers_module modules/mod_headers.so
LoadModule deflate_module modules/mod_deflate.so

finally add this line to your .htaccess file.

SetOutputFilter DEFLATE
