Hi Guys,
I'm currently upgrading a web site. There is a link to "http://travel.ian.com/index.jsp"
What kind of link is that

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That link is what is called a sub-domain (http://en.wikipedia.org/wiki/Subdomain).

You can replace the www of any site with a different name, which creates a sub-domain of your site.  This is pretty common for people to do, however, there are discussions as to the SEO value of utilizing this practice.  From what I understand, using a sub-directory is better than a sub-domain, as Google treats sub-folders as parts of a whole site, which will help with internal link-building, etc.

Sub-domain = name.sitename.com
Sub-directory = www.sitename.com/name

Here is an article from Google's Matt Cutts on sub-domains vs sub-directories (http://www.mattcutts.com/blog/subdomains-and-subdirectories/).

Hope this helps.

Did you open it? It points to Hotels.com
Actually, for me it went to TravelNow.com (SS attached).  Strange.  Did it really take you to Hotels.com?
