I am reading, and attempting to determine the best approach for "passing a message back and forth between these (web servers) "boxes" and the ability to POST to an external ip/URL php file and get back its response if possible.
any assistance here would be a great service.
also how come the chapter/examples 19* are not in the example folders?

The reason the Chapter 19 code isn't included in the sample code file is that there aren't any full examples that you can run. The code shown in Chapter 19 is bits of code to do things, but there isn't a full example.
