GT.M , HTTP URL request and webserver

in GT.M

1.
http framework cycle
how I create a link between:
 client html http requests-web server-GT.M program response
 as stateless usage, but with ability to handle sessions ID ?
2.
what tools I need to activate such a proccess ?
are they all buil-in in GT.M ?

3.
how is the link between webserver and GT.M or it's come directly to
GT.M listner ?
is there a code sample how to use it ?

4.
how is the usage of tcp link (like telnet),
is there also some code sample or link how to activate such a
proccess ?
means GT.M listner+it's parameters ?
