- * Revision 1.57 2007/06/01 16:53:05 fabiankeil
- * Adjust cgi_show_url_info() to show what forward-override{}

- *
- * Revision 1.56 2007/05/21 10:50:35 fabiankeil

- *
- * 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

- * 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

- *
- * Remove outdated comment.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
