*
* Revisions :
* $Log: parsers.c,v $
+ * Revision 1.34 2001/10/07 18:50:55 oes
+ * Added server_content_encoding, renamed server_transfer_encoding
+ *
+ * Revision 1.33 2001/10/07 18:04:49 oes
+ * Changed server_http11 to server_http and its pattern to "HTTP".
+ * Additional functionality: it now saves the HTTP status into
+ * csp->http->status and sets CT_TABOO for Status 206 (partial range)
+ *
+ * Revision 1.32 2001/10/07 15:43:28 oes
+ * Removed FEATURE_DENY_GZIP and replaced it with client_accept_encoding,
+ * client_te and client_accept_encoding_adder, triggered by the new
+ * +no-compression action. For HTTP/1.1 the Accept-Encoding header is
+ * changed to allow only identity and chunked, and the TE header is
+ * crunched. For HTTP/1.0, Accept-Encoding is crunched.
+ *
+ * parse_http_request no longer does anything than parsing. The rewriting
+ * of http->cmd and version mangling are gone. It now also recognizes
+ * the put and delete methods and saves the url in http->url. Removed
+ * unused variable.
+ *
+ * renamed content_type and content_length to have the server_ prefix
+ *
+ * server_content_type now only works if csp->content_type != CT_TABOO
+ *
+ * added server_transfer_encoding, which
+ * - Sets CT_TABOO to prohibit filtering if encoding compresses
+ * - Raises the CSP_FLAG_CHUNKED flag if Encoding is "chunked"
+ * - Change from "chunked" to "identity" if body was chunked
+ * but has been de-chunked for filtering.
+ *
+ * added server_content_md5 which crunches any Content-MD5 headers
+ * if the body was modified.
+ *
+ * made server_http11 conditional on +downgrade action
+ *
+ * Replaced 6 boolean members of csp with one bitmap (csp->flags)
+ *
+ * Revision 1.31 2001/10/05 14:25:02 oes
+ * Crumble Keep-Alive from Server
+ *
+ * Revision 1.30 2001/09/29 12:56:03 joergs
+ * IJB now changes HTTP/1.1 to HTTP/1.0 in requests and answers.
+ *
+ * Revision 1.29 2001/09/24 21:09:24 jongfoster
+ * Fixing 2 memory leaks that Guy spotted, where the paramater to
+ * enlist() was not being free()d.
+ *
+ * Revision 1.28 2001/09/22 16:32:28 jongfoster
+ * Removing unused #includes.
+ *
+ * Revision 1.27 2001/09/20 15:45:25 steudten
+ *
+ * add casting from size_t to int for printf()
+ * remove local variable shadow s2
+ *
+ * Revision 1.26 2001/09/16 17:05:14 jongfoster
+ * Removing unused #include showarg.h
+ *
+ * Revision 1.25 2001/09/16 13:21:27 jongfoster
+ * Changes to use new list functions.
+ *
+ * Revision 1.24 2001/09/13 23:05:50 jongfoster
+ * Changing the string paramater to the header parsers a "const".
+ *
+ * Revision 1.23 2001/09/12 18:08:19 steudten
+ *
+ * In parse_http_request() header rewriting miss the host value, so
+ * from http://www.mydomain.com the result was just " / " not
+ * http://www.mydomain.com/ in case we forward.
+ *
+ * Revision 1.22 2001/09/10 10:58:53 oes
+ * Silenced compiler warnings
+ *
+ * Revision 1.21 2001/07/31 14:46:00 oes
+ * - Persistant connections now suppressed
+ * - sed() no longer appends empty header to csp->headers
+ *
* Revision 1.20 2001/07/30 22:08:36 jongfoster
* Tidying up #defines:
* - All feature #defines are now of the form FEATURE_xxx
* CRLF -> LF
*
* Revision 1.11 2001/05/29 20:11:19 joergs
- * '/* inside comment' warning removed.
