hi, how do I know which should I put it in response.redirect( )?

I have 2 page now  ( a is writted by VB .. I can't modify it.. , b is writted by C#)

page a is shows many title... and once user click one of them it will direct to page b. page b will shows content which user click from page a..

 so that's why I'm wondering .. is it ok? get parameter in url when we are in page b...
