Re: server down error status.

Well, I am getting pretty puzzled by this behavior. I had tried the samples 
that come with the project, and again did so, and no matter which terminate 
handler or timeout I set, any programs gets stuck as ..

HTDoConnect. WOULD BLOCK `w0352496'
Host Event.. WRITE passed to 
`http://w0352496:9080/sampleserv/servletsample2'
HTDoConnect. WOULD BLOCK `w0352496'
Host Event.. WRITE passed to 
`http://w0352496:9080/sampleserv/servletsample2'
HTDoConnect. WOULD BLOCK `w0352496'

In this case there is NO webserver runnning on w0352496:9080 (which happens 
to be my own NT machine). Does anyone have a solution to exiting gracefully 
when there is no web server running on a valid host.

Also, say if I try to connect to a non-existant machine, the program does 
exit.

Thanks,
Tanmay
