Subject: Re: general/2202: .cgi programs in user directories run  without suexec

 suexec sets things up so that CGIs run as a different user than what the
 web server runs as.  This is done through either virtualhosts with user
 and group directives or through ~userdir requests.
 Without suexec, the normal way to do things is that all CGIs are executed
 by the user the web server runs as.  This is perfectly acceptable in many
 environments and is not necessarily a security risk.  If people want
 ~userdir CGIs to run as the user instead, they have to use suexec.  If
 they don't, they don't run suexec and CGIs run as they always have on
 nearly every Unix web server in the history of the web.
