WMLScript » URL » URL.getReferer

Syntax:
URL.getReferer()

Returns the smallest relative URL.

The URL.getReferer function returns the smallest relative URL for the resource (the referer) that called the current file. This returned URL is relative to the base URL of the current file. The empty string "" is returned if the current file does not have a referer. Note that local function calls cannot change the referrer.

This function does not take a parameter.
