[SR-Users] Pseudo-variables and branches

[Daniel-Constantin Mierla]

Hello,

$rd is the domain from the latest r-uri, not from original r-uri. Can 
you check to be sure there is no revert_uri() used somewhere around?

If still a problem, then load debugger module, set its parameter 
cfgtrace to 1 and send the log messages here to see what actions are 
executed, maybe some revert the uri inside.

Cheers,
Daniel
