POST-ing an HTTP request from Rabbit Webserver

Hi All

Anyone of you know how to POST an initial(like a browser) HTTP request to another server using the Dynamic C HTTP.LIB?
Like this?

POST /GWS/WS.asmx/GetLog HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Content-Length: length

I want to submit a request for another web service from a Rabbit Web server

Any help will be greatly appreciated
