Description
Creates an absolute, platform-appropriate path that is equivalent to the value of
relative_path
,
appended to the base path. This function (despite its name) can accept an absolute or relative
path in the
relative_path
parameter
The base path is the currently executing page’s directory path. It is stored in
pageContext.getServletContext().
Returns
A string. If the relative path contains a trailing forward slash or backward slash, the return value
contains the same trailing character.

History
ColdFusion MX: Changed behavior for the
relative_path
parameter: this function can now
accept an absolute or relative path in the
relative_path
parameter. To resolve a path, this
function uses virtual mappings that are defined in the ColdFusion Administrator. This function
does not reliably use virtual mappings that are defined in IIS, Apache, or other web servers.
Parameters
Usage
If the parameter or the returned path is invalid, the function throws an error.
These examples show the valid constructions of relative_path:
•
ExpandPath( "*.*")
•
ExpandPath( "/")
•
ExpandPath( "\")
•
ExpandPath( "/mycfpage.cfm")
•
ExpandPath( "mycfpage.cfm")
•
ExpandPath( "myDir/mycfpage.cfm")
•
ExpandPath( "/myDir/mycfpage.cfm")
•
ExpandPath( "../../mycfpage.cfm")
Parameter Description
relative_path Relative or absolute directory reference or file name, within the current directory,
(.\ and ..\) to convert to an absolute path. Can include forward or backward slashes.
