44 * Revision 1.8 1996/02/12 10:09:25 adam
45 * New parameter to wproto_init: directory root for the FIFOs (instead
46 * of using preprocessor defines FIFODIR/FIFOROOT).
48 * Revision 1.7 1996/01/24 08:26:55 adam
49 * All tcl commands prefixed with egw_ (except the html command).
51 * Revision 1.6 1996/01/12 13:08:07 adam
52 * CGI script passes name of lock file to the shell. The server will not close
53 * the response FIFO until this file becomes unlocked. This method handles
54 * cancel operations much better.
56 * Revision 1.5 1996/01/12 10:05:21 adam
57 * If script name ends with ';' HTTP/GET/Expires will be defined.
58 * The cgi interface only reads final handshake if response from
59 * server (shell) was zero-terminated [If it isn't it probably died].
61 * Revision 1.4 1995/11/06 10:51:18 adam
62 * End of response marker in response from wsh/wproto to wcgi.
63 * Shells are respawned when necessary.
65 * Revision 1.3 1995/10/27 15:12:11 adam
66 * IrTcl incorporated in the gateway.
67 * Better separation of script types.
68 * Z39.50 gateway scripts entered.
70 * Revision 1.2 1995/10/23 16:55:41 adam
71 * A lot of changes - really.
73 * Revision 1.1 1995/10/20 11:49:27 adam
74 * First version of www gateway.
