ASP.NET site maintenance tip

I am planning to shift my site from one host to other. Any best practices to follow while moving the site?

• my site is always accessed using both http://mysomesite.com and http://www.mysomesite.com. I have not set redirection from http to http://www. Should I be doing it now?

When the nameservers are updated, how do I inform the users? Any way in ASP.NET to put the开发者_如何学C site in maintenance mode?

UPDATE: I meant to ask should I redirect http://mysomesite.com to http://www.somesite.com or is it OK to leave it like that.

Regarding your last question, yes there is, create a file called App_Offline.htm, and place it in the root directory. It will end all sessions and show only that page. Rename/delete it to stop it.

Regarding the first part, well that's more sys admin, but yes, you should have non-www and www both go to your site, in general.
