I'm using the NNTP component to retreive bodies of news articles. If I want
to download two or more articles simultaneously I guess I need to use
threads.

The GetBody function only returns once the whole body has been retrieved so
how is it supposed to be used in a thread?  Do I need to use one of the Indy
thread components, or something completely different?

Thanks in advance
Anthony

I don't know 100% for sure, but I believe that most NNTP servers do not
allow you to download multiple articles simultaneusly.

The only way I could think of is to actually have multiple connections to
the server, each connection in a VCL TThread object.  That way you can
download multiple articles simultaneously.

Again, this all depends on the server you are connecting to.

Correct.

You would need to establish multiple connections to the server, one
connection per thread.

True enough.  That is why newsreaders that support multiple connections
usually provide an option to allow the user to specify the maximum number of
connections to make at a time :-)

Many NNTP servers limit the number of simulteaneous connections per IP 
though, so watch out for connection refusals.
