Subject RE: [users@httpd] Hacked the website replace the page
Date Mon, 09 May 2005 02:13:44 GMT

Does no one use cgi wrap anymore? I thought that the best way to handle 
this kind of thing is to run PHP as a CGI first off, and then use something 
like wrap to isolate users. Yes, lesser performance, but people running on 
shared servers get what they pay for, and it certainly makes sense to take 
their security first and performance second.
