Use the Mappings page of the ColdFusion Administrator to add, update, and delete logical aliases for paths to directories on your server. ColdFusion mappings apply only to pages that ColdFusion processes with the cfinclude and cfmodule tags. If you save CFML pages outside of the web_root directory (or whatever directory is mapped to "/"), you must add a mapping to the location of those files on your server.

Assume that the "/" mapping on your server points to C:\coldfusion8\wwwroot, but that all of your ColdFusion header pages reside in C:\2002\newpages\headers. For ColdFusion to find your header pages, you must add a mapping in the ColdFusion Administrator that points to C:\2002\newpages\headers (for example, add a mapping for /headers that points to C:\2002\newpages\headers). In the ColdFusion pages located in C:\coldfusion8\wwwroot, you reference these header pages using /headers in your cfinclude and cfmodule tags.
