It it works with a browser but not curl, then there must be something done
differently between the two. It's theoretically possible that the remote
site is doing something more sophisticated than checking the User-Agent
to determin whether to let a request through or not, but it's unlikely.

Try comparing the log output you see from a browser request using Wireshark
or LiveHTTPHeaders or equivalent with the log output you see doing the
request with curl (after enabling debugging, of course). Once you find
the difference, you can match the curl request.
