fsockopen() and http://sitename.com connection

hello
i must connect to a remote server. Here is the type of addy I have been given:

http://blah.site.com:8090/One/two/three

How can I open the socket?
is it just as easy as:



fsockopen('blah.site.com', 8090);


it doesn't seem to work though.
Can anyone shed some lights please?

thanks in advance for your time :)
