PHP supports output compression via PHP's ouput buffering features and the zlib extension. The simplest way is to use the <code>ob_start ('ob_gzhandler')</code> or use the configuration options <code>zlib.output_compression</code> and <code>zlib.compression_level</code> Alternatively, you can use PEAR's excellent HTTP_Compress class that will handle everything related to HTTP_Compression for you... ]]>
