I believe the correct term for what you're talking about is "Reverse Proxy".
Try a google-search on that term (or "reverse HTTP proxy" may provide better
results... haven't checked), and you should get some good explanations.
For a reverse proxy, all requests from the public for the http server are
sent to that machine/proxy first, which then typically provides some
checking/filtering, and then hands the request to the 'real' http server.
Many reasons for doing this, one of the most pervasive being security.

The difference is:
That proxy type serves one ip and typically recieves incoming requests from
only it. I want to recieve requests from everywhere, and relay to my ip,
without them knowing my ip,,,, and those other things i mentioned.

http://devel.squid-cache.org/rproxy/
I was told several times that if i installed Squid on a remote shell, my
account would be closed. There was another reverse proxy i forgot the name
of, i looked into it a couple years ago and forgot the name of it..
http://www.at32.com/doc/rproxy.htm
Is a list of good reasons to have such a device. All major web serve
companies must have one. I don't see why the world denies me the use of
one.

is also a good one, and shows apparently some people pay only $50 for it. I
need it to run remotely, since running it here would stupidly mean none of
the bandwidth-protection in the proxy script would be useable. Of course, i
did offer a lot more than $50 for it to run remotely.....
And apparently java can do this.

I have called it that also. But if people do not understand "proxy", they sure
won't understand reversing one. That would be like a reverse gear on a
motorcycle, who in their right mind would not just push the 800lb bike
backwards out of a tight spot themselves? Rather like threads and goto in
that regard.

Security is also the "reason" the hosting companies have denied letting me
run one. They seem to think if it dials out only to me, millions of others will
use it to dial out to flood ebay or something. Yeas, i know that is screwed
thinking, but most of the world is this way.
