The deliver parameter

Earlier versions required a fully-qualified url, however, starting with version 1.03, the operation of the deliver parameter has been enhanced. Three forms of url are now accepted.

Fully-qualified url e.g. deliver=http://www.example.com/downloads/example.exe
Domain-relative url e.g. deliver=/downloads/example.exe
Domain-relative urls must begin with the / character

Domain-wildcard url e.g. deliver=http://*/downloads/example.exe
The * character represents the domain name.
This syntax permits other protocols such as ftp to be specified without including the domain name.

NOTE
When the domain name is not specified, it is determined by inspecting the environment variable HTTP_HOST. To ensure that this works correctly on your server, you should enter the following :-
http://www.yourdomain.com/counters/unicounter.pl?name=test&deliver=http://*/
When working correctly, you should be redirected to the domain's home page.
