The HTTP Relay module requires ipv6 if remote server has ipv6.
Example settings: LOCATION /foo CALL http://www.roxen.com/
LOCATION /googletest CALL http://www.google.com/
In both these examples the Relay module tries to use the ipv6 adress provided from the DNS. This will not work, when Roxen WebServer doesn't have ipv6 set up.
A typicall error in the browser reads: 504 Gateway Timeout: Connection to remote HTTP host failed
