Yeah, try this
Open a stream connection (ie like a telnet connection) to port 80 on the
server
and wait for a connection.. then send a string

GET /Filename HTTP/1.0
<Blank Line>

and the server will return the page to you.

ie for my homepage
telnet www.omen.net.au 80
<connect>
GET /~bcampbel/index.htm HTTP/1.0
<blank Line>

--------------------
spews out page here...
<disconnect>

It's that easy
