使用ColdFusion获取URL的子域

<cfset url = "http://www.example.com/">
<cfset subdomain = "">
<cfset domain = "">

<cfif Find("://", url)>
    <cfset url = RemoveChars(url, 1, Find("://", url) + 2)>
    <cfif Find("/", url)>
        <cfset url = RemoveChars(url, Find("/", url), Len(url) - Find("/", url) + 1)>
    </cfif>
    <cfif Find(".", url)>
        <cfset domain = RemoveChars(url, 1, Find(".", url) - 1)>
        <cfset subdomain = RemoveChars(url, Find(".", url) + 1, Len(url) - Find(".", url) - Len(domain) - 1)>
    </cfif>
</cfif>

<cfoutput>
    Subdomain: #subdomain#<br>
    Domain: #domain#
</cfoutput>
