44 * Revision 1.7 1996/01/24 08:26:55 adam
45 * All tcl commands prefixed with egw_ (except the html command).
47 * Revision 1.6 1996/01/12 13:08:07 adam
48 * CGI script passes name of lock file to the shell. The server will not close
49 * the response FIFO until this file becomes unlocked. This method handles
50 * cancel operations much better.
52 * Revision 1.5 1996/01/12 10:05:21 adam
53 * If script name ends with ';' HTTP/GET/Expires will be defined.
54 * The cgi interface only reads final handshake if response from
55 * server (shell) was zero-terminated [If it isn't it probably died].
57 * Revision 1.4 1995/11/06 10:51:18 adam
58 * End of response marker in response from wsh/wproto to wcgi.
59 * Shells are respawned when necessary.
61 * Revision 1.3 1995/10/27 15:12:11 adam
62 * IrTcl incorporated in the gateway.
63 * Better separation of script types.
64 * Z39.50 gateway scripts entered.
66 * Revision 1.2 1995/10/23 16:55:41 adam
67 * A lot of changes - really.
69 * Revision 1.1 1995/10/20 11:49:27 adam
70 * First version of www gateway.
