Question

I have a MVC3 application which follows PRG pattern, I am looking for a best way to define navigation rules to my application. For example I have application with pages A, B, C and D. Lets say A is a logon page. After user logon successfully, user will be redirected to page B. Now I do not want let the user to type url of page C in the address bar and get access to page C (Page C should be accessible only after POST ing page B or from Page D back button) I have to setup similar rules for all other pages as well (lets say when user is in page D, should not allow them to get into Page B)

currently I have one option where I can check the @Request.UrlRefferer property to get the source of the every request and decide which page to redirect to. I am not sure this is a best solution.

Appreciate your feedbacks!!

Answer 1

I end up doing this task as below:

1. On successful completion of every page, save the page Name in database
2. When user request for a new page, simply check the page they have completed last from database and decide what to do.

I chooses this approach simply because it will definitely help during Problem Solving/Troubleshooting once application is in Production, which is huge for me.

Thanks everyone for your responses!
