How to create website specific configuration files while running multiple ASP.NET websites on a single code base?

I want to create 2 websites on a single code base in asp.net. lets for say :

www.domain1.com

www.domain2.com

I need to keep all the appsetting key name sames but with different values for each of the websites.So i need to maintain two web.config files in my code base.

After exploring on internet , i found to keep both of the web.config files in different folders in the code base.

Bow the problem is, how can i link each of the different web.config file with its corrosponding Virtual directory for each the website because both of the Virtual directories wil开发者_如何转开发l target the same folder of code base.

I really neede it as i have to finish this work within this week.

Thanks

If you really want to serve both site from one application/virtual directory, the only solution I can come up with is as follows:

<appSettings>
  <add key="setting[www.domain1.com]" value="foo" />
  <add key="setting[www.domain2.com]" value="bar" />
  ...

And then access these accordingly:

var setting = ConfigurationManager.AppSettings["setting[" + request.Domain + "]"];
