A very nice contorl/project (recommend by my Chief Architect) for a very common problem which we all face when we need to secure only specific pages. Below is the link.

I applied this in my production environment and it is working perfectly. All related issues are solvable/configurable.

Some useful email exchanges between me and Matt(the guy who made this) are added below as comments.

Let me summarize the steps (If your using Visual Studio 2010)

1. Install-Package SecuritySwitch from VS > Tool > Extension Manager > Search “SecuritySwitch” install it, more details can be found on http://nuget.org/packages/SecuritySwitch.
2. Above step set-up every thing for you for your development environment. (Put some attributes in you web.config, add some dlls etc)
3. Now you need to specify your secure pages in web.config inside securitySwitch>paths>
4. These are important attributes mode=”" baseInsecureUri=”" baseSecureUri=”"
5. For the staging or production deployment please go through with the below comments.
