Ehhmm...
I think... I think.. I do.. ;-)
I believe there exists a (html) file containing links and descriptions...
Then there also is a form, in which I guess the visitor enters a URL to search for, and the form is then put to use to look for the requested URL in the html file containing links and descriptions.
Okay.. well I thought I understood, but now I'm not sure anymore..
Perhaps Shaju can give a better example?
