Using HTTP w/o the HTML test client

Hi Friends,

I am trying a scenario wherein I want to send HTML page form data to XI to RFC. Using HTML Test client I am able to acheive that. Now I wanted it to try it w/o using HTML test client.

I referred to the below URL for that purpose.

Link:[http://help.sap.com/saphelp_nw04/helpdata/en/43/64db4daf9f30b4e10000000a11466f/frameset.htm]

It states I need to specify the URL : http://<hostname:port>/<path>?<query-string>

I need to know that where should I specify this.

Is it in the HTML page in the form action part?

If yes, I believe it would be hardcoded. Can I avoid hard coding?

What about the payload? Where are its details mentioned?

Please guide.

Regards,

Shiben
