Using GZIP compression in web servers using .HTACCESS

I use PHP CodeIgniter support for GZIP compression but I had to do some changes in a CI library for to compress javascript libraries but thanks to Joan Piedra and his post in jQuery Mail list I see this solution better:

in the .htaccess:

<ifmodule mod_headers.c>

  <ifmodule mod_deflate.c>
 # Compress some text file types

  AddOutputFilterByType DEFLATE text/html text/css text/xml application/x-javascript

  

  # Deactivate compression for buggy browsers

  BrowserMatch ^Mozilla/4 gzip-only-text/html

  BrowserMatch ^Mozilla/4\.0[678] no-gzip

  BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

  </ifmodule>

</ifmodule>

NOTE: It doesn't work with Apache version < 2 web servers. You need deflate and headers module.
