- * Revision 1.45 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the
- * memory that was used.
- *
- * Revision 1.44 2002/03/16 21:51:00 jongfoster
- * Fixing free(NULL).
- *

- * Re-enabled automatic config reloading
- *
- * Revision 1.36 2002/01/22 23:46:18 jongfoster
- * Moving edit_read_line() and simple_read_line() to loaders.c, and
- * extending them to support reading MS-DOS, Mac and UNIX style files
- * on all platforms.
- *
- * Modifying read_config_line() (without changing it's prototype) to
- * be a trivial wrapper for edit_read_line(). This means that we have
- * one function to read a line and handle comments, which is common
- * between the initialization code and the edit interface.
- *
- * Revision 1.35 2002/01/17 21:03:08 jongfoster
- * Moving all our URL and URL pattern parsing code to urlmatch.c.
- *
- * Renaming free_url to free_url_spec, since it frees a struct url_spec.
- *

- *
- * Revision 1.31 2001/10/26 17:39:01 oes
- * Removed csp->referrer
- * Moved ijb_isspace and ijb_tolower to project.h
- *
- * Revision 1.30 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. 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.
- *

- * Cosmetic: Moving unloader funcs next to their
- * respective loader funcs

- * Fixed line continuation problem
- *
- * Revision 1.13 2001/05/31 21:28:49 jongfoster
- * Removed all permissionsfile code - it's now called the actions
- * file, and (almost) all the code is in actions.c
- *
- * Revision 1.12 2001/05/31 17:32:31 oes
- *
- * - Enhanced domain part globbing with infix and prefix asterisk

- * Revision 1.10 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * 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.)
- *

- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS

- * skipping.
