+ * File : $Source: /cvsroot/ijbswa/current/filters.h,v $
*
* Purpose : Declares functions to parse/crunch headers and pages.
* Functions declared include:
*
* 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.
+ * - 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
+ * original URL.
+ *
+ * Revision 1.22 2006/07/18 14:48:46 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
* Revision 1.20.2.2 2004/10/03 12:53:32 david__schmidt
* Add the ability to check jpeg images for invalid
* lengths of comment blocks. Defensive strategy
