I have a SharePoint 2010 installation at my customer looking a bit odd. We have three web applications (intranet, mysite and cooperation) in three different web applications on the IIS serving HTTP-requests on port 80. There is also a wild card SSL certificate installed on the server which can be used for any application under the domain *.customer.com.
There are also three other web applications on the server for HTTPS-requests on port 443 serving the same content in a different folders within C:\inetpub\wwwroot\ and of course a web application to serve Central admin.
Coming from the ASP.NET-world this setup seems odd, since I would – just add a binding on port 443 to serve HTTPS-request on the same web application serving HTTP-requests on port 80. So instead of having seven web applications, with redundant files, I would use only four.
But I’m kind of new to SharePoint, and there might be something I’m unaware of… What am I missing in this setup?
