building url manually...

Question

Hi, Is there a way to embed a session id into a url manually? When a user has completed a transaction, I want to email them download links with the session id embedded in the url. This is what I've tried and it doesn't quite work the way I thought it would. Response.ApplyAppPathModifier("/FolderB/download.aspx") The above call is made from FolderA so what it returns is ("FolderA/(45drmerfyujwn4ihb3tsqkim)/FolderB/download.aspx This is not what I would expect. I didn't expect it to attach FolderA. Is there a different way to do this?
