It's fairly clear to me that it is _not_ the correct solution. I was
thinking along the same lines as Tony w/ regards to using a separate
UDP connection.
Maybe I was just missing something, but I didn't see how either of
the initial suggestions would actually work.
The first method forced all of the status info to come before any of
the data was transferred which seems silly. If I have a server
generating information, it may as well be sending it as it is generated.
The second method, I don't understand at all. I've already received one
HTTP/1.0 response so how/where am I getting the "HTTP/1.0 205 Starting
search..." messages?

Agreed. It is silly to use TCP for information which is obviously
ideally suited for UDP.
