It's a parameter containing a number of seconds that HTTPAPI should sit 
and wait before giving up.  You just pass the number of seconds, and if 
HTTPAPI can't connect, or is connected but receives no bytes in that 
many seconds, it will give up.

Normally, 60 seconds.  It's controlled by the HTTP_TIMEOUT constant in 
the CONFIG_H source member.

You can change the default by editing the CONFIG_H source member and 
recompiling everything that uses it (including HTTPAPI itself, just call 
the INSTALL program.)

However, I don't really see the value in changing the default...  If you 
have a particular app that needs a different timeout, just pass a 
different number of seconds in that application.

That's tricky...  HTTPAPI doesn't really know whether the web server is 
down.  All it knows is whether it can or can't communicate with it.  For 
example, someone could come and pull out the network cable to the system 
running HTTPAPI.  The Web server might still be up -- but HTTPAPI can't 
communicate with it -- it has know way of knowing whether it's up or not.

Typically, a web service will send you back an error if the server is up 
but the application isn't responding.  However, that's not something 
HTTPAPI has any control over -- it's on the server side.

If HTTPAPI can't get a response, how can it possibly know whether the 
server is up?!
