Ok. At this point, we *think* that the customer *may have* done whatever 
unspecified proxy voodoo for the Google Calendar address, that they'd 
done to make Google Maps work when called from Java.

But if they have, it doesn't work from HTTPAPI. (Quite frankly, given 
what you said, I'd be pleasantly surprised if it did.)

All I know about the aforementioned "proxy voodoo" is that it involves a 
host table entry that maps the desired domain into an IP address in one 
of the "local" blocks. I'm guessing that's the proxy's IP address. But I 
haven't a clue what the proxy port would be.

Given that my own proxy experience consists entirely of my having 
written a very crude Telnet proxy, many years ago, about all I know 
about HTTP proxies is what my much-abused grey cells can comprehend of 
what you've told me.

Assuming that they actually *did* do their "proxy voodoo," and that it 
*didn't* work for HTTPAPI, I'm obviously going to have to ask them some 
questions, in order to build a proper call to http_setProxy(). And I'm 
not entirely convinced that they're going to understand a simple "What's 
the proxy port?" (Given my recent *BNDDIR problem, this seems to be a 
case of someone who's totally clueless [i.e., me] trying to get 
information on someone who's both clueless and paranoid [i.e., the 
customer].)

And oh, yes, I did manage to fix the *BNDDIR problem.
