Subject: remove x-powered-by from php 5.2.3 cgi module
From: bri@cshell.gr (sotiris karavarsamis)

i've got a webserver which runs php 5.2.3 via fastcgi, and i've recently 
tried to remove the x-powered-by header for security reasons. however, 
changing the php.ini expose-php directive value to off made no 
difference. After searching a little on google for this problem, it came 
out that there is no configuration directive for this, and so i created 
a little patch for the cgi sapi module to solve it. you can find the 
patch at http://docs.cshell.gr/patches/xpoweredby-cgiphp5.2.3.patch . 
hope it helps many people who encounter the same problem. you can also 
argue for this at http://www.cshell.gr/?p=113 .
