/***************************************
** Title.........: PHP4 HTTP Compression Speeds up the Web
** Version.......: 1.10
** Author........: catoc <catoc@163.net>
** Filename......: gzdoc.php
** Last changed..: 25/08/2000
** Requirments...: PHP4 >= 4.0.1
** PHP was configured with --with-zlib[=DIR]
** Notes.........: Dynamic Content Acceleration compresses
** the data transmission data on the fly
** code by sun jin hu (catoc) <catoc@163.net>
** Most newer browsers since 1998/1999 have
** been equipped to support the HTTP 1.1
** standard known as "content-encoding."
** Essentially the browser indicates to the
** server that it can accept "content encoding"
** and if the server is capable it will then
** compress the data and transmit it. The
** browser decompresses it and then renders
** the page.
** Useage........:
** No space before the beginning of the first '<?' tag.
** ------------Start of file----------
** |<?
** | include('gzdoc.php');
** | print "Start output !!";
** |?>
** |<HTML>
** |... the page ...
** |</HTML>
** |<?
** | gzdocout();
** |?>
** -------------End of file-----------
