Getting the server hostname in CFML

Updated on November 13, 2023

Need to know a server's hostname, not the http server name using CFML (ColdFusion). Try this:
<cfset inet = CreateObject("java", "")>
<cfset inet = inet.getLocalHost()>

Getting the server hostname in CFML was first published on December 02, 2003.

why not just use #cgi.server_name#?

That returns different values depending on the web site domain. This method always returns the server's hostname. I'm not sure why you would need that specifically, but someone asked for it, and this is the solution I came up with.

Hi Jason,

What I'm using here is part of the standard Java API. Documentation for it can be found here:

The service factories in ColdFusion MX are not documented by Macromedia at all, they don't really want you messing with them. When CFMX first came out I posted some undocumentation here: it doesn't cover the service factory, but it does cover some other features.

"documentation out there on Macromedia Java variables and functions"

its called fusdocs (Coldfusion MX javadocs)
