So this proves this functionality. However, there are a couple of issues here . Invariably, what has been
created here are host named web applications with a single host name. Host-named site collections have
a single URL and they do not support alternate access mappings and are always considered to be in the Default
Microsoft says “If you need to support site collections responding to multiple host-name URLs, consider
using path-based site collections with alternate access mappings instead of host-named site collections”.
This could cause problems as in my situation; a web application had already been created. To get around
this I would recommend the following:- Extend the web application and when extending it, use the original
host header of the originating web application, and then in the URL field, insert the URL to be created as an
alternate access mapped url. Lets use an example where an SSL site needed to be made of via the Internet,
so the Url is https://internet.sharepoint.local . Select the web application and then click on the authentication
provider button to ‘look’ at the existing authentication providers”. This would have been set as default i.e.
the original authentication provider created when the web application was created. Close the Authentication
Extend the web application by clicking on “the Extended” button.
You will now be brought to the extend web application to another IIS web site area. Here, you then configure
the host header and the right url for the Internet zone. Since we are also configuring a secure site, then change
the port to use 443 as well. In the host header field, ensure that this is not populated.
In the security configuration setting, ensure that “Use secure sockets layer” is selected.
Next, scroll down to the public url section and enter the url, and re-enter the url as
https://internet.sharepoint.local and select the zone as Internet.
You would then be able to use the extended site as an Internet site. Please note though, you would not able to
access the site until a SSL certificate has been applied and this will be covered in a later story.
