Subject Re: Strange problem with Embperl 2.0b9 + httpd 2.0.40
Date Mon, 21 Jul 2003 15:38:08 GMT
Hi,

You should not use CGI inside Embperl because it will try to read the
form fields again and conflict with Embperl, and make your app BIG.

For your escaping use the $req->Escape from Embperl (I don't know if it
is available in Embperl2 - Gerald?).

Regards,
