* Revisions :
* $Log: cgisimple.c,v $
+ * 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
+ * - Escaped ampersands in generated HTML.
+ * - Renamed re-filter-filename to re-filter-filenames
+ *
+ * Revision 1.42 2006/11/21 15:43:12 fabiankeil
+ * Add special treatment for WIN32 to make sure
+ * 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+ * Remove outdated comment.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
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
+ * Revision 1.35.2.7 2006/01/29 23:10:56 david__schmidt
+ * Multiple filter file support
+ *
+ * Revision 1.35.2.6 2005/07/04 03:13:43 david__schmidt
+ * Undo some damaging memory leak patches
+ *
+ * Revision 1.35.2.5 2005/05/07 21:50:55 david__schmidt
+ * A few memory leaks plugged (mostly on error paths)
+ *
+ * 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
+ * - Prevent line wrap beween "View/Edit" link buttons on status page
+ * - Some (mostly irrelevant) fixes for Out-of-mem-case handling
+ *
+ * Revision 1.35.2.2 2003/04/03 13:48:28 oes
+ * Don't show "Edit" buttons #ifndef FEATURE_CGI_EDIT_ACTIONS
+ *
+ * Revision 1.35.2.1 2002/07/04 15:02:38 oes
+ * Added ability to send redirects to send-banner CGI, so that it can completely mimic the image blocking action if called with type=auto
+ *
+ * Revision 1.35.2.1 2002/07/01 17:32:04 morcego
+ * Applying patch from Andreas as provided by Hal on the list.
