No (unless by chance you have called one of your datasets "Godiva" or something
like that).

Correct - the WMS service includes some non-standard custom operations
(GetMetadata) that serve all the JSON documents for the Godiva site. There are
no requests outside the WMS service endpoint.

If the WMS service is not on port 80 the port number needs to be included in
the request.
Hope this helps,
Jon

Hi Jon:
But does the Godiva service by any chance make a request that includes the
name Godiva in it? Otherwise the only requests you make are to the wms service
is that correct? I have on my own computer a very small version of what we have
set up but without the proxies, and Godiva works fine there, so I am pretty
certain it is in the proxying.
One last question - do you include the port number when you form the URL to
make the request (ie what is the basis for what you use for the requests?
Port numbers give us a lot of heartburn. A can probably proxy those if I know
what is being sent.
Thanks,
-Roy
