Dave,
Thanks for the reply, but this won't work in this instance.
Further to a previous post, I have a page with CfTree, when one of the items
is dbl-clicked, I jump to a page with a form.
The CFTreeItemKey value gets put into a form variable and the form is
automatically submitted (<body onload="submit">) to an ISAPI DLL I've
written.
This breaks the "Back" button as when the user clicks back from my DLL they
go back to the auto submit form.
I was hoping to add some code to this page which looks to see where the user
has come from and go on to whatever page necessary.
i.e <Cfif FindNocase("finduserby",#HTTP_REFERER#) NEQ 0>
We have come from the CFtree page so go on the the DLL
Body and Form stuff goes here.
Cfelse
We have come back from the DLL so
<Body onload="history.go(-1)">
</Body>
</Cfif>
Now I can't interact with CF Session vars from the DLL so I was hoping to
use
HTTP_REFERER but CFTREE (although it has to be within a CFForm) doesn't
cause a Form Submit so it looks like I'm stuck.
I may have to look at creating a CFX in Delphi unless someone has a better
idea.

There's no guaranteed way to do this using CGI variables, but you could
track this information in a Session variable, changing the value of the
variable on every page request.
