I create an asp.net master page and a several pages that use this master page.

I'm using the asp.net membership provider classes to handle the login ect.

No I have been told that my asp.net pages will be used from an IFRAME inside an HTML page.

How will this affect my asp.net pages ? Will I have to get rid of my master page ? Will my security still work ? And how does this affect all my dll references inside my asp.net web project ? Will all of this still work ?

P.S (I'm a noob web developer,this is my first Web project so any tips would be much appreciated)

Kind Regards and thanks in advance.
