Gabe,

Your information is 95% correct. UNIX servers are not forgiving regarding file
name case sensitivity. "index.html" is not the same file as Index.html.
However, www.quessing.com and WwW.QUessIng.Com are the same; DNS does not rely
on case--regardless of what platform you are using to store your zone file.

The reason for this: there is only one program that does DNS: it is called
BIND. There is a
port (version) of BIND for about every OS or OS flavor, and they all have to
follow the exact same rules (it is the only way DNS will work).

You CANNOT register two different domains: "quessing.com" and "QUESSING.COM"

CAVEAT: In IIS 4.0, under NT, there are some aspects of the service that are
case
sensitive. Specifically, when calling scripts from within a file, script.asp is
not the same as Script.Asp. For site visitors, there is no difference in case:
"DEFAULT.HTM" is identical to "default.htm" or "DeFaUlT.HtM."

This information applies across the board to all UNIX and NT Web servers. We've
played with Netscape, and Apache for UNIX, and it held true. We've also worked
with Netscape, IIS, and Apache for NT, which covers close to 95% of the server
market. So, we can't say our information is 100% accurate, but it's close.

&gt;I am working on course materials for an advanced searching class and
I <br>
&gt;was wondering about whether trainers mention case sensitivity in
URLs. <br>
&gt;The domain part of the address is not case sensitive since it relies
on <br>
&gt;a domain server. The directory path and filename are case sensitive
<br>
&gt;only if the website is hosted from a UNIX server. Is this information
<br>
&gt;correct? I have found conflicting opinions after running an Internet
<br>
&gt;search.<br>
