I would like to set up a shared directory that can be used by all my subdomains (i.e. Philly.CommuterClub.org, Scranton.CommuterClub.org, forum.commuterclub.org, classifieds.commuterclub.org, etc.) so they can share common files when I use subdomain URL's.

For example, if I enter the URL this way: http://www.commuterclub.org/classifieds/ the logo on the top left displays fine, but if I enter it this way: http://classifieds.commuterclub.org/ the logo does not display because it doesn't know how to find the logo file, looking for http://classifieds.commuterclub.org/images instead of http://www.commuterclub.org/images which is where the logo file is stored.

Is there a way to do this, or will I have to replicate all the common files into each subdomain (there are a lot of them)

Thanks for any assistance you may offer.

Just to clarify the above, the problem is I am using a common header with the path Request.ServerVariables("SERVER_NAME")/images for each subdomain so they can all share the same header file.

So I guess the question is if I can rewrite the Request.ServerVariables("SERVER_NAME") parameter to subdomain.commuterclub.org

Anyone have any ideas? Did I make this clear or is it confusing?

Take one global variable called
strsiteurl = http://www.commuterclub.com

and then concatenate it with all image url like this
<%=strsiteurl%>/images/logo.gif instead of Request.serverVariables

one typo mistake
strsiteurl = "http://www.commuterclub.com"

Can you tell me what rule you have written to achieve your desired result because i am also looking for something similar. Let me explain you my exact requirement may you can help me out.

my current three dynamic urls are
http://www.sitename.com/Folder/index.asp?str1=value1
http://www.sitename.com/Folder/index.asp?str1=value1&str2=Value2
http://www.sitename.com/Folder/index.asp?str1=value1&str2=Value2&str3=Value3

Now what i want
http://value1.sitename.com/Folder/
http://value1.sitename.com/Folder/Value2.html
http://value1.sitename.com/Folder/Value1/Value3.html

Hence i want use Value1 as a subdomain and rest of the parameter as html pages. The reason to have folder is may be my future i want to create one sub-domain physically on the server and that time both will conflict with each other.

Thanks
Yatin

You can not rewrite SERVER_NAME (all IIS variables are read-only) but you can rewrite Host: header which directly affects server name. But I would not recommend you to do this since it may affect all web applications running in the same domain. Yatin's idea with the global application variable is much better.
For example, you could set some custom header with the help of ISAPI_Rewrite and use this header instead of the SERVER_NAME variable.
