68757 asp or php login

I need people to be able to log in, then automatically get redirected to a specific webpage based on their username and password. If their username is rejected, they will go to a default page that asks them to please log back in. I'll need the actual code, and if the work is done in asp (I dont know the best code to do it in) then I might need a little help integrating it onto our web server. I need the work done extremely quickly, possibly overnight if possible.
