+            [Content Extensions] Cache domain actions
+            https://bugs.webkit.org/show_bug.cgi?id=146817
+
+            Reviewed by Benjamin Poulain.
+
+            Right now we run regular expressions on the domain every time we have any rules that match with if-domain or unless-domain.
+            This caches the results of running regular expressions on the domain of the main document's url so we only need to
+            run those regular expressions when the main document changes domain.  We also spend less time adding unused actions into HashSets.
+
+            All behavior is covered by existing api tests, but I added some to explicitly test if-domain and unless-domain with multiple load types.
