So, it's time to do a real, live, - * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__ - * (native). Both versions will work, but using __OS2__ offers multi-threading. - * - * Revision 1.4 2001/10/23 21:48:19 jongfoster - * Cleaning up error handling in CGI functions - they now send back - * a HTML error page and should never cause a FATAL error. (Fixes one - * potential source of "denial of service" attacks). - * - * CGI actions file editor that works and is actually useful. - * - * Ability to toggle JunkBuster remotely using a CGI call. - * - * You can turn off both the above features in the main configuration - * file, e.g. if you are running a multi-user proxy. - * - * Revision 1.3 2001/10/14 22:12:49 jongfoster - * New version of CGI-based actionsfile editor. - * Major changes, including: - * - Completely new file parser and file output routines - * - edit-actions CGI renamed edit-actions-for-url - * - All CGIs now need a filename parameter, except for... - * - New CGI edit-actions which doesn't need a filename, - * to allow you to start the editor up. - * - edit-actions-submit now works, and now automatically - * redirects you back to the main edit-actions-list handler. - * - * Revision 1.2 2001/09/16 17:05:14 jongfoster - * Removing unused #include showarg.h - * - * Revision 1.1 2001/09/16 15:47:37 jongfoster - * First version of CGI-based edit interface.

(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 1.5 2001/05/27 22:17:04 oes - * - * - re_process_buffer no longer writes the modified buffer - * to the client, which was very ugly.

(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 1.12 2001/05/27 22:17:04 oes - * - * - re_process_buffer no longer writes the modified buffer - * to the client, which was very ugly.

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!

(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. - */ - -#ifdef STATIC_PCRE -# include "pcre.h" -#else -# include -#endif - -#ifdef STATIC_PCRS -# include "pcrs.h" -#else -# include -#endif - -#ifdef STATIC_PCRE -# include "pcreposix.h" -#else -# include -#endif - -#ifdef AMIGA -#include "amiga.h" -#endif /* def AMIGA */ - -#ifdef _WIN32 -/* - * I don't want to have to #include all this just for the declaration - * of SOCKET.
