Web server compression?

The best way to understand web server compression is to think of sending ZIP files
instead of uncompressed files from your web server to your web user. Sending less data
over the network will minimize network latency and your web users will get the file
faster.
The same thing applies to web spiders, as the major ones support HTTP 1.1. In fact,
search engines would appreciate the fact that they will need to use a lot less network
bandwidth to do the same work.
Web server compression is a technology used on the web server where you are hosting
your pages. If you have full control of the web server, you can set up this compression
to occur automatically for all websites or pages this server is hosting.
If you do not have this luxury, you can set this up in your code. To set up web server
compression in PHP, you can use the following PHP code:
<?php
ob_start("ob_gler");
?>
<HTML>
<body>
<p>This is the content of the compressed page.</p>
</body>
</HTML>
You can enable web server compression in your code in another way that is even easier
than the approach we just discussed. You can use the php.ini file that usually sits in
your root web folder. If it does not exist, you can create it. You can also place this file
in your subfolders to override the root php.ini settings.
