Top posting (comprehensively quoting someone else's message below one's own)
normally indicates lack of comprehensive reading. Did you understand
_anything_ of what I wrote? It seems to me that you didn't.

It works fine. Google is rather successful, you know.

You've got it all backwards. Any checking you do before the URL construction
would take place in the _browser_, so it would be inherently and
unconditionally unreliable. You cannot, thank &Deity;, control what my
browser does. If you offer some JavaScript code that performs a preliminary
check, to save _my_ time, I might be persuaded to let my browser execute
JavaScript on your page. Just might. You still couldn't know whether I had
done that and whether the data has been checked when it reaches your server.
