I would recommend making forum/test.aspx to a actual C1 page. You can still use your .master page as template for this page.
- Create a xml template in the C1 console under Layouts
- Name the template Common
-
paste this as content in the template
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head />
<body />
</html>- Create the page and choose Common as the template
- voila
