+ * CGI script passes name of lock file to the shell. The server will not close
+ * the response FIFO until this file becomes unlocked. This method handles
+ * cancel operations much better.
+ *
+ * Revision 1.13  1996/01/12  10:05:20  adam
  * If script name ends with ';' HTTP/GET/Expires will be defined.
  * The cgi interface only reads final handshake if response from
  * server (shell) was zero-terminated [If it isn't it probably died].
