NCSA httpd allows you to serve your documents from a single directory, which can be any physical directory. The World Wide Web browsers never see the name of this physical directory, allowing you to move your documents into different directories (or to a larger disk) without rewriting your HTML documents and telling everyone who may be using your server about the move.
In addition, if heavily publicized documents move from your server to a different one, NCSA httpd allows you to easily point the users to the new location of the documents. With some browsers, the user will not even notice the change.
For example, my personal page is not
on hoohoo anymore, it's on www.ncsa.uiuc.edu
. By
following the above hyperlink (which goes to hoohoo
)
you'll get referred to the new version anyway.
