asp.net redirect

This is a simple appliction. What I want is to create a generic login screen (do not worry about the logic behind logging in). What I am interested in is 2 asp.net pages (c#) and one c# object. One page is the login page. One page is a content page. If I go to the content page, it will call the c# object (non-visual object). This object needs to redirect the webpage to the login page. Hitting ok, on the login page redirects back to the content page. This is a prototype application that I am going to be incorperating into another project. I would anticipate that the non visual class would have a method that takes in the Request ?? and the URL to go back to. The deliverable is for a clean prototype. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform c#
