Is the client application a standalone executable or does it need to be a component of some larger system?
thanks a lot for your reply!

i just need to figure out how to read the page now. it's been long since i've done any programming and didn't deal much with the web.

now i've got an idea from you about the algorithm so that should make it easier.

no, it doesn't need to display the page itself. the client application will be a standalone executable as it's going to be just a handy tool to improve system monitoring.
