  * Revisions   :
  *    $Log: filters.h,v $
+ *    Revision 1.33  2008/02/23 16:57:12  fabiankeil
+ *    Rename url_actions() to get_url_actions() and let it
+ *    use the standard parameter ordering.
+ *
+ *    Revision 1.32  2008/02/23 16:33:43  fabiankeil
+ *    Let forward_url() use the standard parameter ordering
+ *    and mark its second parameter immutable.
+ *
+ *    Revision 1.31  2007/10/19 16:53:28  fabiankeil
+ *    Add helper function to check if any content filters are enabled.
+ *
+ *    Revision 1.30  2007/09/29 10:21:16  fabiankeil
+ *    - Move get_filter_function() from jcc.c to filters.c
+ *      so the filter functions can be static.
+ *    - Don't bother filtering body-less responses.
+ *
+ *    Revision 1.29  2007/09/28 16:38:55  fabiankeil
+ *    - Execute content filters through execute_content_filter().
+ *    - Add prepare_for_filtering() so filter functions don't have to
+ *      care about de-chunking and decompression. As a side effect this enables
+ *      decompression for gif_deanimate_response() and jpeg_inspect_response().
+ *    - Change remove_chunked_transfer_coding()'s return type to jb_err.
+ *      Some clowns feel like chunking empty responses in which case
+ *      (size == 0) is valid but previously would be interpreted as error.
+ *
+ *    Revision 1.28  2007/09/02 15:31:20  fabiankeil
+ *    Move match_portlist() from filter.c to urlmatch.c.
+ *    It's used for url matching, not for filtering.
+ *
+ *    Revision 1.27  2007/04/30 15:02:18  fabiankeil
+ *    Introduce dynamic pcrs jobs that can resolve variables.
+ *
+ *    Revision 1.26  2007/03/13 11:28:43  fabiankeil
+ *    - Fix port handling in acl_addr() and use a temporary acl spec
+ *      copy so error messages don't contain a truncated version.
+ *    - Log size of iob before and after decompression.
+ *
  *    Revision 1.25  2007/01/12 15:36:44  fabiankeil
  *    Mark *csp as immutable for is_untrusted_url()
  *    and is_imageurl(). Closes FR 1237736.
