* File : $Source: /cvsroot/ijbswa/current/filters.h,v $
*
* 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.
+ *
+ * Revision 1.24 2006/12/29 18:30:46 fabiankeil
+ * Fixed gcc43 conversion warnings,
+ * changed sprintf calls to snprintf.
+ *
* Revision 1.23 2006/11/28 15:19:43 fabiankeil
* Implemented +redirect{s@foo@bar@} to generate
* a redirect based on a rewritten version of the
