I would need just the md5 of the contents text. It's a easy way to see 
if a page has changed without getting the full page and the the 
synchronized part I have is the same as the one on the server.

like the ETAG or similar?

Actually I wanted something that would give me the functionality of md5. 
it would tell me if the page as changed and it would also tell me that 
the contents I have saved are the same as the contents of the page.
