This site is an example of a web site that has a sub domain established.

This page is available from two different URLs

http://www.caves.org/nss/

http://www.nss.caves.org

Both URLs point to the same directory location on the web server.


What is a sub domain and why would I want one?

A sub domain offers a group or person with a web site on www.caves.org the ability to have a unique domain name for promotional or vanity purposes. For example you can request the sub domain of www.mygrotto.caves.org or www.mysection.caves.org.

A sub domain name will generally be easier for someone to write down or remember than a domain name with a directory structure. For example: When encountering spelunkers in a cave it might be easier to say "Check out our web site at www.dug.caves.org"  rather than saying "Check out our web site at www.caves.org/grotto/dug/".

A sub domain can  be pointed to any subdirectory on the web server.

You do not get unique email address capability with a sub domain like you do with a regular domain. However all @cave.org email addresses with work with all sub domains.  For example: webmaster@caves.org is the same address as webmaster@nss.caves.org as is webmaster@dug.caves.com.

A group or person requesting a sub domain name does not own the sub domain name. It is merely an extension of the existing www.cave.org domain name which the NSS owns.

The cost of a sub domain is $xx/year.


Notes:

A page referenced by a sub domain can not refer to a page or directory above its by a relative name. It must referenced by its fully qualified name. Here is an example of this:

If you came here via http://www.caves.org/nss/ then this link will take you up one level to the NSS home  page: ../index.html

If you came here via http://www.nss.caves.org then this link  ../index.html will not take you to the NSS home page. Of course this link http://www.caves.org/index.html will always take you to the NSS home page.
