  * Revisions   :
  *    $Log: cgi.c,v $
+ *    Revision 1.103  2008/03/21 11:13:57  fabiankeil
+ *    Only gather host information if it's actually needed.
+ *    Also move the code out of accept_connection() so it's less likely
+ *    to delay other incoming connections if the host is misconfigured.
+ *
+ *    Revision 1.102  2008/02/23 16:33:43  fabiankeil
+ *    Let forward_url() use the standard parameter ordering
+ *    and mark its second parameter immutable.
+ *
+ *    Revision 1.101  2008/02/03 15:45:06  fabiankeil
+ *    Add SOCKS5 support for "Forwarding failure" CGI page.
+ *
+ *    Revision 1.100  2007/10/17 18:40:53  fabiankeil
+ *    - Send CGI pages as HTTP/1.1 unless the client asked for HTTP/1.0.
+ *    - White space fix.
+ *
+ *    Revision 1.99  2007/08/05 13:42:22  fabiankeil
+ *    #1763173 from Stefan Huehner: declare some more functions static.
+ *
+ *    Revision 1.98  2007/05/14 10:33:51  fabiankeil
+ *    - Use strlcpy() and strlcat() instead of strcpy() and strcat().
+ *
  *    Revision 1.97  2007/04/09 18:11:35  fabiankeil
  *    Don't mistake VC++'s _snprintf() for a snprintf() replacement.
