*
* Revisions :
* $Log: filters.h,v $
+ * 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.
