I just started at a new job as a asp.net developer. The place I am working, a small college, has several web pages made with old school html, vbscript, php, and asp (not asp.net). My boss wants their websites to have a menu system to navigate through the pages. I started a asp.net master page with a header, footer, and menu on the left. However, now, I am trying to get the school's websites to appear in the contentplaceholder. Is there someway to insert a pages content (example www.google.com) into the contentplaceholder? I was thinking of using a combination of frames and asp master pages but all I get are errors so far.

The folder's name is the same of value in Session["id"], like this: string id = Session["id"]; string temp = "~/temp" + id; temp = Server.MapPath(temp); DirectoryInfo dr = new DirectoryInfo(temp); Directory.Delete(dr.FullName);
