+ *
+ * Revision 1.28 2001/09/13 23:05:50 jongfoster

+ *
+ * Revision 1.26 2001/07/30 22:08:36 jongfoster

+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.25 2001/07/29 18:43:08 jongfoster

+ * Introduced http->user_agent
+ *
+ * Revision 1.23 2001/07/18 12:32:23 oes
+ * - Added ACTION_STRING_DEANIMATE
+ * - moved #define freez from jcc.h to project.h

+ *
+ * Revision 1.20 2001/06/29 21:45:41 oes
+ * Indentation, CRLF->LF, Tab-> Space
+ *
+ * Revision 1.19 2001/06/29 13:33:36 oes
+ * - Improved comments
+ * - Introduced http_request.host_ip_addr_str
+ * - Introduced http_response.head_length
+ * - Introduced config.my_ip_addr_str, config.my_hostname,
+ * config.admin_address and config.proxy_info_url
+ * - Removed config.proxy_args_header and config.proxy_args_trailer,
+ * renamed config.proxy_args_invocation to config.proxy_args
+ * - Removed HTML snipplets and GIFs
+ * - Removed logentry from cancelled commit
+ *
+ * Revision 1.18 2001/06/09 10:57:39 jongfoster
