How do I add the ability to browse a Sharepoint site from another URL

so from the internal network, browsing the sharepoint site //phxsp works great.  I also want to open it up to the outside network for those that know the URL and authenticate.  portal.company.com

obviously I know that I need to set up the dns for the domain to point to the IP address on the server, but is there any other confgs in the IIS7 and or Sharepoint Portal Admin that I need to set up?

My biggest concern right now, is that if I browse the IP of the server directly, some of the content it missing becuase its referenced as //phxsp rather than its internal IP address.  Some images, and or web parts just dont work like when done without the hostname.  So is this something that I can fix? Thanks.

Hello,

you can extend the web application as described in this Technet article:

http://technet.microsoft.com/en-us/library/cc261698.aspx

Also see the articles following that one.

With regards to missing content because of the referencing: Using complete and absolute references like http://myserver/mylibrary/myitem is a very bad idea, because, as you have just found out, it is not portable. You need to use relative referencing instead, for example /mylibrary/myitem then it does not really matter what the server's name or address or host name is.

You need to change all the absolute references to relative ones if you want to access the site with another host name.

cheers, teylyn
