using same 443 port on different web applications on same server for https RRS feed

  • Question

  • We would like to use same 443 port on different web applications on same server for https sharepoint sites.

    How can we easily do that. We already have one web app with one site collection running for one client with https and wild card certificate. Now we would like to create another web app for another client with same 443 port and https.

  • There are 3 ways that IIS can use to differentiate between web apps (web sites).

    1. Separate IP addresses.  To do this bind more than one IP address to your server's Network card or add a second network card.  You can then change the binding for each Web app to use a different IP address.  Configure DNS to point each name to the write IP address. (This is the one I would suggest)
    2. Different Port numbers - You can't use this because you want to use the same port
    3. Host headers. - Using Host Headers at the WEb App level is discouraged in 2013 since you have to have at least one web application with no host header in order to use "SharePoint 2013 Apps".
