SharePoint 3.0 – Alternate Access Mapping

Posted by Brian Gough on May 22, 2007


How can I render the site using both http:// and https://?

We set up a anonymous access WSS site without SSL on it. After a time, we realized that we really should enable SSL so when our employees log in to the site, their credentials will be encrypted. Yes, the rest of the content is also encrypted but in our case we are more concerned about the credentials than the content, especially since the site is open to the public.

After getting the certificates installed and IIS set, we still needed to be able to use both http: and https:. Why? Because our site is open to the public, we want them to use the http:// link; some of our content points to external sites using http:// and we do not want ‘joe user’ to be constantly bothered with the notification window asking them if they want to display both secure and non-secure content.

So what did we do to make this happen?


We used a seldom talked about capability ( trying to find other words for ‘features’ since a thing called ‘features’ is a new part of SharePoint 3.0 <wink>) called Alternate Access Mapping (AAM). Rather than try to duplicate what other more learned people have already written, here is a link that goes into more details about AAM….

My needs are rather simple compared to all that you can use AAM for. I just need the same content served up when a user enters http: or https:.


  • Logon to the Central Administration site
  • Click on ‘Operations’.
  • Click ‘Alternate access mappings’ under the Global Configuration section.
  • You will see a list of all your SharePoint sites.
  • To the far right of the menu bar you will see a dropdown list labeled ‘Alternate Access Mapping Collection:’ Click the drop down and select ‘Change alternate access mapping collection’.
  • Select the site you want to add the AAM to.
  • Click ‘Edit Public URLs’ in the menu bar. This will open a page showing your URL in the zone it is defined in. in my case it is in ‘Default’.
  • You can see there are several options to enter a value ( Default, Internet, intranet, Custom, and Extranet). Enter the full URL using https: into one of these areas. I was able to enter it into any one of those fields and got the same behavior, but I chose Intranet for mine since it is really just for our employees to use.
  • Click ‘Save’.

You should now be able to view your site using either http: or https:.

Good luck and good coding.
