+ * Revision 1.94 2007/03/21 12:23:53 fabiankeil
+ * - Add better protection against malicious gzip headers.
+ * - Stop logging the first hundred bytes of decompressed content.
+ * It looks like it's working and there is always debug 16.
+ * - Log the content size after decompression in decompress_iob()
+ * instead of pcrs_filter_response().
+ *
+ * Revision 1.93 2007/03/20 15:21:44 fabiankeil
+ * - Use dedicated header filter actions instead of abusing "filter".
+ * Replace "filter-client-headers" and "filter-client-headers"
+ * with "server-header-filter" and "client-header-filter".
+ * - Remove filter_client_header() and filter_client_header(),
+ * filter_header() now checks the shiny new
+ * CSP_FLAG_CLIENT_HEADER_PARSING_DONE flag instead.
+ *
+ * Revision 1.92 2007/03/05 13:25:32 fabiankeil
+ * - Cosmetical changes for LOG_LEVEL_RE_FILTER messages.
+ * - Handle "Cookie:" and "Connection:" headers a bit smarter
+ * (don't crunch them just to recreate them later on).
+ * - Add another non-standard time format for the cookie
+ * expiration date detection.
+ * - Fix a valgrind warning.
+ *
+ * Revision 1.91 2007/02/24 12:27:32 fabiankeil

+ *
+ * Revision 1.90 2007/02/08 19:12:35 fabiankeil

+ * sed() parses server headers; only adjust the
+ * Content-Length header if the page was modified.
+ *
+ * Revision 1.89 2007/02/07 16:52:11 fabiankeil
+ * Fix log messages regarding the cookie time format
+ * (cookie and request URL were mixed up).
+ *
+ * Revision 1.88 2007/02/07 11:27:12 fabiankeil
+ * - Let decompress_iob()
+ * - not corrupt the content if decompression fails
+ * early. (the first byte(s) were lost).
+ * - use pointer arithmetics with defined outcome for
+ * a change.
+ * - Use a different kludge to remember a failed decompression.
+ *
+ * Revision 1.87 2007/01/31 16:21:38 fabiankeil
+ * Search for Max-Forwards headers case-insensitive,
+ * don't generate the "501 unsupported" message for invalid
+ * Max-Forwards values and don't increase negative ones.
+ *
+ * Revision 1.86 2007/01/30 13:05:26 fabiankeil
+ * - Let server_set_cookie() check the expiration date
+ * of cookies and don't touch the ones that are already
+ * expired. Fixes problems with low quality web applications
+ * as described in BR 932612.
+ *
+ * - Adjust comment in client_max_forwards to reality;
+ * remove invalid Max-Forwards headers.
