TCP Server Deux is a 4th Dimension component which provides a cross-platform, flexible TCP level server. TCP Server Deux allows 4D developers to run one or more higher level protocol servers in a single 4D database without have to code for multiple listeners, threading, messaging, or many of the other functional elements that often complicate custom servers in 4th Dimension. TCP Server Deux works on top of TCP Deux and BASh and works with Internet ToolKit v2.0.x and Internet ToolKit v2.5.x. Now compatible with 4D v6.8.x, as well!

With TCP Server Deux, a 4th Dimension developer can easily develop a server available through multiple protocols. For instance, having a Domain Name Server with an integrated web interface is a simple matter; the same is true of an email server, available through both SMTP and POP3, with a HTTP interface over a custom port for administering the settings and accounts in the email server. TCP Server Deux handles all of the listeners, threading, multiple processes, and communications necessary in a custom server written in 4D. By handling all of these issues as a TCP server, and with suitable hooks available for processing of requests and setting responses, it is then a simple matter to merely write parsers for higher level protocols that reside on the TCP layer.

TCP Server Deux works with other components already available from Deep Sky Technologies, Inc.

The TCP Deux component is used for all TCP level access within the TCP Server Deux component.
And, of course, the BASh component is used by TCP Server Deux for a lot of the basic functionality available within the server component.

TCP Server Deux does require a robust TCP plugin for access to the TCP communication layer from within 4th Dimension. Though TCP Deux does provide compatibility with 4D Internet Commands, unfortunately 4D IC does not provide a robust, and asynchronous, TCP listener routine. Because of this, TCP Server Deux only works with Internet ToolKit (ITK) v2.0.x and v2.5.x. If used with ITK v2.5.x in conjunction with an ITK SSL Server license, full access to the SSL layer is available for all functionality within TCP Server Deux.
