URL references matching entries in the Additional DNS Name List of the host are rewritten
with the Published DNS Name. The Web Server Host Name does not need to be included in this
list.
The DNS names in the Exclude DNS Name List specify the names that the rewriter should skip
and not rewrite.
NOTE: Excludes in the Exclude DNS Name List are processed first, then the includes in the
Additional DNS Name List. If you put the same DNS name in both lists, the DNS name is rewritten.
The following sections describe the conditions to consider when adding DNS names to the lists:
"Determining Whether You Need to Specify Additional DNS Names" on page 44
"Determining Whether You Need to Exclude DNS Names from Being Rewritten" on page 45
Determining Whether You Need to Specify Additional DNS Names
Sometimes Web pages contain URL references to a hostname that does not meet the default criteria
for being rewritten. That is, the URL reference does not match the Web Server Host Name or any
value (IP address) in the Web Server List. If these names are sent back to the client, they are not
resolvable.

The page on the data.com Web server contains two links, one to an image on the data.com server and
one to an image on the graphics.com server. The link to the data.com server is automatically
rewritten to novell.com, when rewriting is enabled. The link to the image on graphics.com is not
rewritten, until you add this URL to the Additional DNS Name List. When the link is rewritten, the
browser knows how to request it, and the Access Gateway knows how to resolve it.
You need to include names in this list if your Web servers have the following configurations:
If you have a cluster of Web servers that are not sharing the same DNS name, you need to add
their DNS names to this list.
If your Web server obtains content from another Web server, the DNS name to this additional
Web server needs to rewritten.
