+ * created based on client and server headers.
+ *
+ * Revision 1.60 2007/03/20 15:16:34 fabiankeil
+ * Use dedicated header filter actions instead of abusing "filter".
+ * Replace "filter-client-headers" and "filter-client-headers"

+ *
+ * Revision 1.59 2007/01/25 13:38:20 fabiankeil

+ *
+ * Revision 1.53 2006/08/31 16:25:06 fabiankeil
+ * Work around a buffer overflow that caused Privoxy to
+ * segfault if too many trusted referrers were used. Good
+ * enough for now, but should be replaced with a real
+ * solution after the next release.
+ *
+ * Revision 1.52 2006/07/18 14:48:46 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)

+ *
+ * Revision 1.50.2.1 2002/07/26 15:19:24 oes

+ * name change related issues
+ *
+ * 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).
+ *
+ * Revision 1.43 2002/03/16 20:28:34 oes

+ * 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.
+ *

+ * 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.
+ *
+ * Revision 1.29 2001/10/23 21:38:53 jongfoster

+ * - Permanently turned off WIN_GUI_EDIT
+ * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
+ *
+ * Revision 1.23 2001/07/20 15:51:54 oes
+ * Fixed indentation of prepocessor commands
+ *
+ * Revision 1.22 2001/07/20 15:16:17 haroon
+ * - per Guy's suggestion, added a while loop in sweep() to catch not just
+ * the last inactive CSP but all other consecutive inactive CSPs after that

+ * Revision 1.15 2001/06/07 23:14:14 jongfoster
+ * Removing ACL and forward file loaders - these
+ * files have been merged into the config file.
+ * Cosmetic: Moving unloader funcs next to their
+ * respective loader funcs
+ *
+ * Revision 1.14 2001/06/01 03:27:04 oes
+ * Fixed line continuation problem
+ *
+ * Revision 1.13 2001/05/31 21:28:49 jongfoster
+ * Removed all permissionsfile code - it's now called the actions
