In the mailing list archives, search for "env usertag".
(it is in 

interchange.redhat.com/pipermail/interchange-users/2001-May/007684.html

) After installing this tag, [env 'HTTP_REFERER'] is the previous page (yes, 
it should be 'referer' and not 'referrer'). You can simply use

<a href="[env 'HTTP_REFERER']">Click here to go back to previous page</a>

to have a link to the page before.

If you want to go to the 'previous' page in a form that you might post 
several times, you can create a CGI variable that remembers what 
page you originally came from:

<form method="POST">
[perl]
	my $refer=$Tag->cgi("referring_page");
	if ($refer eq "") { $refer=$Tag->env('HTTP_REFERER'); }
	return <<EOG;
<input type="hidden" name="referring_page" value="$refer">
<a href="$refer">Click here to go back to previous page</a>
EOG
[/perl]
</form>

Hope this helps.
