Webhosting Perl and CGI Scripts

You can upload any perl scripts to anywhere on your web site. You can make a cgi-bin directory if you like, but scripts can be included anywhere on your web site.

For perl, the script should start with #!/usr/bin/perl

Particularly for perl scripts uploaded from windows machines, please upload in ASCII mode not BINARY.

Within the script, the mail program used for sending mail is /usr/lib/sendmail . You should not use this with the -t argument (which find the From and To in the email) but use -f 'from-email-address' 'to-email-address' in place of the -t argument.

A simple mailer is available - Webhosting_Form_Mailer

There are various perl scripts available on the internet, and many books on the subject. You do not have access to php or mysql on the server, and you may have to change the use of sendmail as above.
