Martin,

I was looking at that syntax, but the string I need to test for
'success' is buried further than 256 Bytes into the page.  I saw that
the SEND/EXPECT statements are good for protocol negotiation, but
getting the cookie to the web page is only the first part.  I actually
do use the SEND/EXPECT syntax for the back-end testing, because I need
to verify an XML schema.  

Also, if I understand the SEND/EXPECT schema, even though it uses regexp
to match the incoming strings, I would still havet to code in pretty
much the entire page up to the string I'm looking for, wouldn't I?

So my understanding is that the SEND/EXPECT syntax won't be able to
solve my problem.  

Thoughts?
