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 - see below.

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.

Your scripts have access to the following environment variables :-

QUERY_STRING The query string (bit after the ? in the

URI)

PATH_INFO If after the script there is a / and more

of a path then this is that path

PARAMS The parameters (bit after a ; in the URI)
REQUEST_METHOD PUT or GET
REQUEST_URI The URI (web page) requested
HTTP_HOST Host: header contents

Your web site name

HTTP_AGENT User-Agent: header contents

The browser being used

CONTENT_TYPE Content-type: header contents

Used for form postings

CONTENT_LENGTH Content-length: header contents

Number of bytes in PUT file

SCRIPT_NAME The name of the script being run
HTTP_COOKIE Cookie: header contents
HTTP_FROM From: header contents
HTTP_REFERER Referer: header contents

The page this link came from

REMOTE_USER If a login was required, this is set to the

user name

REMOTE_ADDR The remote IP address.

This could be an IP6 or IP4 address.
