Conditional Redirection

I would like a comprehensive understanding of the conditions under which I can redirect a visitor to another page.

I am aware of unconditional redirection such as the META|REFRESH, and conditional redirection such as NO FRAMES (if visitor's browser doesn't support frames) or NO SCRIPT (if visitor's browser doesn't support Javascript).

I beleive there are ways to redirect based on other conditionals, such as browser version.  Are there other conditionals, such as the visitor's domain name, on which I can base an automatic link to a designated page?

To redirect depending on browser:
if (navigator.appName.indexOf("Netscape") != -1)
  location.href = "netscape.htm";
if (navigator.appName.indexOf("Microsoft") != -1)
  location.href = "ie.htm";
else
  location.href = "otherbrowser.htm";

Forgot to mention...the code I posted i JavaScript.
Use it like this:
<SCRIPT LANGUAGE="JavaScript">
<!--
if (navigator.appName.indexOf("Netscape") != -1)
  location.href = "netscape.htm";
if (navigator.appName.indexOf("Microsoft") != -1)
  location.href = "ie.htm";
else
  location.href = "otherbrowser.htm";
// -->
</SCRIPT>

Martinag is right that you can base it on browser, but you can use a much more exhaustive list than just netscape microsoft.  There's also the version numbers, and then there's opera, and a few other strage ones.
And of course you can redirect based on screen resolution, colors, and a few more thing that you can check.  All of this is done via javascript.  Some other means may be possible, but JavaScript is the most browsewr compatible method.
Also, you mentioned:  "visitor's domain name" and this cannot be done via javascript, but I think Java may have access and there are ways for javascript and java to communicate.  But when trying to determine domain name or ip address, I use cgi/perl which does a nice job.

If you wanted to use one of these methods or had something specific in mind I can provide code for you.
