Now has seperate header and list_entry * structures. Also added a large sprinking of assert()s to the list * code. * * Revision 1.30 2001/09/13 23:52:00 jongfoster * Support for both static and dynamically generated CGI pages * * Revision 1.29 2001/09/13 23:29:43 jongfoster * Defining FORWARD_SPEC_INITIALIZER * * Revision 1.28 2001/09/13 23:05:50 jongfoster * Changing the string paramater to the header parsers a "const". * * Revision 1.27 2001/08/05 16:06:20 jongfoster * Modifiying "struct map" so that there are now separate header and * "map_entry" structures. This means that functions which modify a * map no longer need to return a pointer to the modified map. * Also, it no longer reverses the order of the entries (which may be * important with some advanced template substitutions). * * Revision 1.26 2001/07/30 22:08:36 jongfoster * Tidying up #defines: * - All feature #defines are now of the form FEATURE_xxx * - Permanently turned off WIN_GUI_EDIT * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS * * Revision 1.25 2001/07/29 18:43:08 jongfoster * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to * ANSI C rules. * * Revision 1.24 2001/07/25 17:20:27 oes * 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 1.22 2001/07/15 17:51:41 jongfoster * Renaming #define STATIC to STATIC_PCRE * * Revision 1.21 2001/07/13 14:03:19 oes * - Reorganized regex header inclusion and #defines to * comply to the scheme in configure.in * - Added csp->content_type and its CT_* keys * - Added ACTION_DEANIMATE * - Removed all #ifdef PCRS * * 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 * Adding definition of BUFFER_SIZE. * Changing struct cgi_dispatcher to use "const" strings. * * Revision 1.17 2001/06/07 23:15:09 jongfoster * Merging ACL and forward files into config file. * Moving struct gateway members into struct forward_spec * Removing config->proxy_args_gateways * Cosmetic: Adding a few comments * * Revision 1.16 2001/06/04 18:31:58 swa * files are now prefixed with either `confdir' or `logdir'. * `make redhat-dist' replaces both entries confdir and logdir * with redhat values * * Revision 1.15 2001/06/04 11:28:53 swa * redirect did not work due to missing / * * Revision 1.14 2001/06/03 11:03:48 oes * Added struct map, * added struct http_response, * changed struct interceptors to struct cgi_dispatcher, * moved HTML stuff to cgi.h * * Revision 1.13 2001/06/01 20:05:36 jongfoster * Support for +image-blocker{}: added ACTION_IMAGE_BLOCKER * constant, and removed csp->tinygif. * * Revision 1.12 2001/06/01 18:49:17 jongfoster * Replaced "list_share" with "list" - the tiny memory gain was not * worth the extra complexity. * * Revision 1.11 2001/06/01 10:32:47 oes * Added constants for anchoring selection bitmap * * Revision 1.10 2001/05/31 21:33:53 jongfoster * Changes for new actions file, replacing permissionsfile * and parts of the config file. Also added support for * list_shared. * * Revision 1.9 2001/05/31 17:32:31 oes * * - Enhanced domain part globbing with infix and prefix asterisk * matching and optional unanchored operation * * Revision 1.8 2001/05/29 20:09:15 joergs * HTTP_REDIRECT_TEMPLATE fixed. * * Revision 1.7 2001/05/29 09:50:24 jongfoster * Unified blocklist/imagelist/actionslist. * File format is still under discussion, but the internal changes * are (mostly) done. * * Also modified interceptor behaviour: * - We now intercept all URLs beginning with one of the following * prefixes (and *only* these prefixes): * * http://i.j.b/ * * http://ijbswa.sf.net/config/ * * http://ijbswa.sourceforge.net/config/ * - New interceptors "home page" - go to http://i.j.b/ to see it. * - Internal changes so that intercepted and fast redirect pages * are not replaced with an image. * - Interceptors now have the option to send a binary page direct * to the client. (i.e. ijb-send-banner uses this) * - Implemented show-url-info interceptor. (Which is why I needed * the above interceptors changes - a typical URL is * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif". * The previous mechanism would not have intercepted that, and * if it had been intercepted then it then it would have replaced * it with an image.) * * Revision 1.6 2001/05/27 22:17:04 oes * * - re_process_buffer no longer writes the modified buffer * to the client, which was very ugly. It now returns the * buffer, which it is then written by chat. * * - content_length now adjusts the Content-Length: header * for modified documents rather than crunch()ing it. * (Length info in csp->content_length, which is 0 for * unmodified documents) * * - For this to work, sed() is called twice when filtering. * * Revision 1.5 2001/05/26 00:28:36 jongfoster * Automatic reloading of config file. * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32). * Most of the global variables have been moved to a new * struct configuration_spec, accessed through csp->config->globalname * Most of the globals remaining are used by the Win32 GUI. * * Revision 1.4 2001/05/22 18:46:04 oes * * - Enabled filtering banners by size rather than URL * by adding patterns that replace all standard banner * sizes with the "Junkbuster" gif to the re_filterfile * * - Enabled filtering WebBugs by providing a pattern * which kills all 1x1 images * * - Added support for PCRE_UNGREEDY behaviour to pcrs, * which is selected by the (nonstandard and therefore * capital) letter 'U' in the option string. * It causes the quantifiers to be ungreedy by default. * Appending a ? turns back to greedy (!). * * - Added a new interceptor ijb-send-banner, which * sends back the "Junkbuster" gif. Without imagelist or * MSIE detection support, or if tinygif = 1, or the * URL isn't recognized as an imageurl, a lame HTML * explanation is sent instead. * * - Added new feature, which permits blocking remote * script redirects and firing back a local redirect * to the browser. * The feature is conditionally compiled, i.e. it * can be disabled with --disable-fast-redirects, * plus it must be activated by a "fast-redirects" * line in the config file, has its own log level * and of course wants to be displayed by show-proxy-args * Note: Boy, all the #ifdefs in 1001 locations and * all the fumbling with configure.in and acconfig.h * were *way* more work than the feature itself :-( * * - Because a generic redirect template was needed for * this, tinygif = 3 now uses the same. * * - Moved GIFs, and other static HTTP response templates * to project.h * * - Some minor fixes * * - Removed some >400 CRs again (Jon, you really worked * a lot! ;-) * * Revision 1.3 2001/05/20 01:21:20 jongfoster * Version 2.9.4 checkin. * - Merged popupfile and cookiefile, and added control over PCRS * filtering, in new "actionsfile". * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration * file error you now get a message box (in the Win32 GUI) rather * than the program exiting with no explanation. * - Made killpopup use the PCRS MIME-type checking and HTTP-header * skipping. * - Removed tabs from "config" * - Moved duplicated url parsing code in "loaders.c" to a new funcition. * - Bumped up version number. * * Revision 1.2 2001/05/17 23:01:01 oes * - Cleaned CRLF's from the sources and related files * * Revision 1.1.1.1 2001/05/15 13:59:03 oes * Initial import of version 2.9.3 source tree * * *********************************************************************/ /* Declare struct FILE for vars and funcs. */ #include /* Need time_t for file_list */ #include /* * Include appropriate regular expression libraries. * Note that pcrs and pcre (native) are needed for cgi * and are included anyway. */ #if defined(REGEX_PCRE) || defined (REGEX_GNU) # define REGEX #endif /* defined(REGEX_PCRE) || defined (REGEX_GNU) */ #ifdef STATIC_PCRE # include "pcre.h" #else # include #endif #ifdef STATIC_PCRS # include "pcrs.h" #else # include #endif #if defined(REGEX_PCRE) # ifdef STATIC_PCRE # include "pcreposix.h" # else # include # endif #endif /* defined(REGEX_PCRE) */ #if defined(REGEX_GNU) # include "gnu_regex.h" #endif #ifdef AMIGA #include "amiga.h" #endif /* def AMIGA */ #ifdef __cplusplus extern "C" { #endif /* * Error codes.
