Reference master page stored at root from sub domain folder in asp.net

I have a folder in the root called secure and I have a sub domain called secure which maps to the secure folder. However, I'm getting the following error:

The virtual path '/MasterPage.master' maps t开发者_如何学JAVAo another application, which is not allowed.

Is there a setting somewhere that I can change or some other way to make this work without making a masterpage within the secure folder that has the same data as the root version?

Can you post your IIS setup a little clearer please. From your description it sounds like you have:

• http://yourserver (root)
• http://yourserver/secure (folder) [is this an application or just a folder?]
• http://secure.yourserver (sub-domain) [maps to same folder as http://yourserver/secure]

EDIT

You could store your master pages in a folder

http://yourserver/layouts/MasterPage.master

Then map that folder to your second web site

http://secure.yourserver/layouts

http://secure.yourserver/layouts/MasterPage.master

Then update your page master references to "layouts/MasterPage.master"
