This might be old but it might help someone anyways!
It looks like you are going to a .asp page that could be blocked.
To unblock asp you need to goto sharepoint central admin - then goto - Opperations - then goto -
Blocked file types .
Check to see if asp is in that list and remove it... If the page exisits than it will take you to the right place otherwise it will redirect you to a 404 page ;) so you would need to change the aexp3.asp to aexp3.aspx to work :)
