XML HTTP command

Hi All

I need some advise as to how to i need to pass a command from my VB application to to a remote network Hardware device to Erase its memory .The communication transport used is HTTP and the communication protocol to talk to the hardware device is XML:

The command is
http://192.168.0.251/cgi-bin/dataProxy? oper= PurgeAllTags

Since I am new to this, I would like to know from anyone as to what my approach should be to accomplish this.My initial understanding of the issue is that I will have to

create a XMLHTTP object from my vb application and use the Open ("POST",....) and the SEND methods.Someone pls help me with this.I would appreciate it if anyone could show me some sample code.Thanks.
