APP Offline.htm.. display an offline page while production deployment

See more:

C#

Hey Guys,

A little help needed here..

I need to display a custom page like 'Deployment in progress', a maintance page while i do my production deployment.

I have a fake idea like i need to create some page Appoffline.htm and place it into c:/inetpub/wwroot folder so IIS see's it first before goin to the application.

My question is how can i redirect to this page only while i do my deployment and not always.
Is it a way through c#? Also any settings needed to be changes in IIS for this?

Also once deployment is completed i need to goto my homepage again and not the maintanance page.

Please suggest a way.

Also my application uses Windows authentication.(does this make any difference in implementation for appoffline page ?)


Thanks!!
Sanman
