Actually, you did it wrong. The whitelist uses "regular expressions" ("regex"), and in regex,  means "any character"; thus   can mean "encyclopediadramaticaase", "encyclopediadramaticabse", "encyclopediadramatica2se, etc. rather than "encyclopediadramatica.se" in particular. You need an "escape character" . In order to identify periods using regex, you use   rather than   alone. You also need   at the beginning of   in order to mark the beginning of the domain so that "notencyclopediadramatica.se" isn't also whitelisted.

Now we mus consider what come after .se. Example: "encyclopediadramatica.se/anypage". We need to escape the forward slash with a backslash and in order to produce "anypage", we need to combine   (any character) with   (repeat the previous character any amount of times, including zero times) in order to produce   (repeat any character any amount of times, including zero times). Finally, we close the string with.

tl;dr: What you should have added was.
