* Revisions :
* $Log: actions.c,v $
+ * Revision 1.54 2008/09/20 10:04:33 fabiankeil
+ * Remove hide-forwarded-for-headers action which has
+ * been obsoleted by change-x-forwarded-for{block}.
+ *
+ * Revision 1.53 2008/05/26 16:04:04 fabiankeil
+ * s@memorey@memory@
+ *
+ * Revision 1.52 2008/04/27 16:26:59 fabiankeil
+ * White space fix for the last commit.
+ *
+ * Revision 1.51 2008/04/27 16:20:19 fabiankeil
+ * Complain about every block action without reason found.
+ *
+ * Revision 1.50 2008/03/30 14:52:00 fabiankeil
+ * Rename load_actions_file() and load_re_filterfile()
+ * as they load multiple files "now".
+ *
+ * Revision 1.49 2008/03/29 12:13:45 fabiankeil
+ * Remove send-wafer and send-vanilla-wafer actions.
+ *
+ * Revision 1.48 2008/03/28 18:17:14 fabiankeil
+ * In action_used_to_be_valid(), loop through an array of formerly
+ * valid actions instead of using an OR-chain of strcmpic() calls.
+ *
+ * Revision 1.47 2008/03/28 15:13:37 fabiankeil
+ * Remove inspect-jpegs action.
+ *
+ * Revision 1.46 2008/03/27 18:27:20 fabiankeil
+ * Remove kill-popups action.
+ *
+ * Revision 1.45 2008/03/24 11:21:02 fabiankeil
+ * Share the action settings for multiple patterns in the same
+ * section so we waste less memory for gigantic block lists
+ * (and load them slightly faster). Reported by Franz Schwartau.
+ *
+ * Revision 1.44 2008/03/04 18:30:34 fabiankeil
+ * Remove the treat-forbidden-connects-like-blocks action. We now
+ * use the "blocked" page for forbidden CONNECT requests by default.
+ *
+ * Revision 1.43 2008/03/01 14:00:43 fabiankeil
+ * Let the block action take the reason for the block
+ * as argument and show it on the "blocked" page.
+ *
* Revision 1.42 2008/02/09 15:15:38 fabiankeil
* List active and inactive actions in the show-url-info's
* "Final results" section separately. Patch submitted by Lee
