Wildcard subdomains (2k3 server, IIS6, & Coldfusion)

Windows 2003 Server, IIS 6, Coldfusion 6.1 - setting up wildcard subdomains

[j0ned]

Anyone familiar enough with coldfusion to know if interpreting wildcard subdomains is possible? For example..

tutorials.domain.com would redirect to
domain.com/get/subdomaindata.cfm?subdomain=tutorials

or

fubar.domain.com would redirect to
domain.com/get/subdomaindata.cfm?subdomain=fubar

etc.. etc.. If not possible with coldfusion, how would I go about accomplishing this (changing httpd or OS is not an option)?

Reading quite a bit; great community here.

Parse CGI.SERVER_NAME :)

And welcome to Webmaster World!

Thanks for the welcoming, this place is great.

Just to clarify, I'd need to include something similar to this in my index.cfm, right? (this is untested)

<cfif #CGI.Server_Name# EQ "tutorials.domain.com">
 <cfinclude template="/subdomains/tutorials.cfm">
<cfelseif #CGI.Server_Name# EQ "support.domain.com">
 <cfinclude template="/subdomains/support.cfm">
<cfelse>
 <regular web-site HTML here for index.cfm>
</cfif>

Thanks for the suggestion! My site is still on my local development server, but I obviously plan on testing some different methods on the production server very soon.

(sorry 'bout the double post)

Alright,

So I just tested the code, and with a little modification everything worked as expected.

Thanks for the quick response!

That's the idea, but I'd probably reduce it a bit, to something like this for easy maintanence, etc:

<!--- length of the root domain, with the leading dot --->
<cfset domainLength = Len(".domain.com")>

<!--- list of all your usable subdomains --->
<cfset subList = "tutorials,support">

<!--- parse server_name to find subdomain --->
<cfset subDomain = Left(CGI.SERVER_NAME, Len(CGI.SERVER_NAME) - domainLength)>

<!--- see if it matches one in your list --->
<cfif ListContains(subList, subDomain)>

 <!--- if matches, load that template --->
 <cfinclude template="/subdomains/#subDomain#.cfm">

<!--- if no match, handle error gracefully --->
<cfelse>

 <!--- Error Handler --->

</cfif>

Or even better, write a UDF (ie, "subDomain()") with the basic logic, so you can simply do this:

<cfinclude template="/subdomains/#subDomain(CGI.SERVER_NAME)#.cfm">

That would be cleaner, and more modular for future code reuse.
