Hi there @iagovar,
so first goes the new value you want to have in table and after you can have multiple matches (keys) upon which replacement should happen. So syntax is following for your use case:
http://www.puccaclub.com, http%3A%2F%2Fwww.puccaclub.com
Just tried it and works fine. Also only exact matches are supported so no wildcards.
Br,
Ivan
