[James Richters]

Thanks! 

Is there some convenient way to get the HTML into a Tstringlist?

Simpleget is a function that returns the page:

S:=TFPHTTPCLIENT.SIMPLEGET('http://10.10.01.01/30000/15');

S will contain the page of HTML.

If you need to send a command, you'll probably need to use SimplePost()
