According to the manual, if ob_gzhander detects that the browser is unable to support deflate or gzip it returns FALSE. Does this mean that if you use ob_start("ob_gzhandler"), any browsers that do not support gzip/deflate will receive a blank page?
I've been having problems with IE6 displaying gzipped pages and adding a test:
<?php
if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) ob_start("ob_gzhandler");
else ob_start();
?>
solved the problem. Surely if ob_gzhandler detects a lack of support for deflation it should return the input unchanged and not FALSE?
