Chris & List,

Thanks for the comments! Only after I posted did I notice that you had
mentioned the 'intermediate' page method earlier. Anyway, the list has an
elaboration on that.

Again, thanks! Its always a good idea to go back to the sources and read up on
the HTTP spec once in a while... BTW, on this point, I have almost always
passed in full URLs because browsers sometimes render the URL of the
intermediate page if you don't. Another reason to read, understand & implement
according to spec...

Yes! Caching is VERY important and I suggest everyone reads or something like it to understand the
different kinds of caching, implementation strangeness & strategies for
getting the results you want.
