Hi, is the cPanel proxy script allowed in x10hosting accounts?
The script is below incase you need it, will i get suspended if i put it on?

// If server is running in CGI-mode HTTP Authentification won't work. If
// $cgimode is "true", cPanel Proxy will hide HTTP Authentification, forcing
// cPanel to fall back on Cookie Authentification.

// Defaults to "true" as it will always works, autodetection may be added
// later.
