HTTP or HTTPS Bookmarks

HTTP or HTTPS bookmarks are generally used to grant access to an intranet portal (for example, a SharePoint or web mail access). These bookmarks are entered in the same format as a URL entered directly into your browser and the ASA rewrites or manages the individual bookmarks and sends them to the client browser. As a result of the rewrite, any requests for the bookmark travels to the ASA.

Whenever a user clicks an HTTPS bookmark, the ASA establishes a direct SSL session between itself and the web or mail server being accessed, and it performs the process of certificate validation on behalf of the client. The client never directly receives a copy of the server's certificate, and therefore the client cannot carry out its own verification/authentication of the server.

This is where ASDM comes in handy when importing the URL list.
