Compressing is one of those optimizations for a website which can be
easily done and still has tremendous effect. Gzip compressing your
files results in less bandwidth being used and a lot less data that
needs to travel all the way to the impatient client.
gzip compressing is a piece of cake when you can use htaccess. You can put the code below in your .htaccess file:
<Files *.js>
SetOutputFilter DEFLATE
< /Files>
<Files *.css>
SetOutputFilter DEFLATE
< /Files>
This
will use an output filter to compress the files. All .js and .css files
within the jurisdiction of this .htaccess file will be sent compressed
to the client.
