That's what I thought.

Ouch. Just fixed the memory problem. I was
stupidly adding instead of re-using the string. That fixed that.

The fetches were taking anywhere from 20-60
seconds each. The remote side is taking a long
time to fetch the parts of the page out of
several databases before it starts sending
results. That's a problem of poor design on their
side that I was hoping to work around.
Thanks for your help.
