+ *
+ * Revision 1.58 2007/07/21 12:19:50 fabiankeil

+ * variables, "final matches" or claim the site's secure.
+ *
+ * Revision 1.57 2007/06/01 16:53:05 fabiankeil
+ * Adjust cgi_show_url_info() to show what forward-override{}
+ * would do with the requested URL (instead of showing how the
+ * request for the CGI page would be forwarded if it wasn't a
+ * CGI request).
+ *
+ * Revision 1.56 2007/05/21 10:50:35 fabiankeil
+ * - Use strlcpy() instead of strcpy().
+ * - Stop treating actions files special. Expect a complete file name
+ * (with or without path) like it's done for the rest of the files.
+ * Closes FR#588084.
+ * - Don't rerun sed() in cgi_show_request().
+ *
+ * Revision 1.55 2007/04/13 13:36:46 fabiankeil
+ * Reference action files in CGI URLs by id instead

+ *
+ * Revision 1.54 2007/04/09 18:11:35 fabiankeil
+ * Don't mistake VC++'s _snprintf() for a snprintf() replacement.
+ *
+ * Revision 1.53 2007/04/08 13:21:04 fabiankeil
+ * Reference action files in CGI URLs by id instead
+ * of using the first part of the file name.
+ * Fixes BR 1694250 and BR 1590556.
+ *
+ * Revision 1.52 2007/02/13 15:10:26 fabiankeil
+ * Apparently fopen()ing in "binary" mode doesn't require
+ * #ifdefs, it's already done without them in cgiedit.c.
+ *
+ * Revision 1.51 2007/02/10 16:55:22 fabiankeil
+ * - Show forwarding settings on the show-url-info page
+ * - Fix some HTML syntax errors.
+ *
+ * Revision 1.50 2007/01/23 15:51:17 fabiankeil
+ * Add favicon delivery functions.
+ *
+ * Revision 1.49 2007/01/20 16:29:38 fabiankeil

+ * Display warning if show-url-info CGI page
+ * is used while Privoxy is toggled off.

+ * Add FEATURE_ZLIB to the list of conditional
+ * defines at the show-status page.
+ *
+ * Revision 1.45 2006/12/28 18:16:41 fabiankeil
+ * Fixed gcc43 compiler warnings, zero out cgi_send_user_manual's
+ * body memory before using it, replaced sprintf calls with snprintf.
+ *
+ * Revision 1.44 2006/12/22 14:19:27 fabiankeil
+ * Removed checks whether or not AF_FILES have
+ * data structures associated with them in cgi_show_status.
+ * It doesn't matter as we're only interested in the file names.
+ *
+ * For the action files the checks were always true,
+ * but they prevented empty filter files from being
+ * listed. Fixes parts of BR 1619208.
+ *
+ * Revision 1.43 2006/12/17 17:57:56 fabiankeil
+ * - Added FEATURE_GRACEFUL_TERMINATION to the
+ * "conditional #defines" section

+ * cgi_send_user_manual opens the files in binary mode.
+ * Fixes BR 1600411 and unbreaks image delivery.
+ *
+ * Remove outdated comment.
+ *
+ * Revision 1.41 2006/10/09 19:18:28 roro
+ * Redirect http://p.p/user-manual (without trailing slash) to
+ * http://p.p/user-manual/ (with trailing slash), otherwise links will be broken.
+ *
+ * Revision 1.40 2006/09/09 13:05:33 fabiankeil
+ * Modified cgi_send_user_manual to serve binary
+ * content without destroying it first. Should also be
+ * faster now. Added ".jpg" check for Content-Type guessing.
+ *
+ * Revision 1.39 2006/09/08 09:49:23 fabiankeil
+ * Deliver documents in the user-manual directory
+ * with "Content-Type text/css" if their filename
+ * ends with ".css".
+ *
+ * Revision 1.38 2006/09/06 18:45:03 fabiankeil
+ * Incorporate modified version of Roland Rosenfeld's patch to
+ * optionally access the user-manual via Privoxy. Closes patch 679075.
+ *
+ * Formatting changed to Privoxy style, added call to
+ * cgi_error_no_template if the requested file doesn't
+ * exist and modified check whether or not Privoxy itself
+ * should serve the manual. Should work cross-platform now.
+ *
+ * Revision 1.37 2006/07/18 14:48:45 david__schmidt

+ *
+ * Revision 1.35.2.4 2005/04/04 02:21:24 david__schmidt
+ * Another instance of:
+ * Don't show "Edit" buttons #ifndef FEATURE_CGI_EDIT_ACTIONS
+ * Thanks to Magnus Holmgren for the patch
+ *
+ * Revision 1.35.2.3 2003/12/17 16:34:15 oes
