I'm not familiar with Websocket! I will look into it, hopefully it is
closer to the standard for the web, THANKS!

However, your statement above is not correct, the reason it is called
FastCGI, is because it maintains a socket to a single process, and
therefore does not need to be re-created for each CGI request.

Right, but that's on the server side. State must also be maintained on the client side, i.e. the browser has to know the status of the current comm. for this session with the server. FastCGI is "kind of like" MOD_PERL in the sense that the server-side process doesn't evaporate after the reply. That doesn't mean FastCGI keeps track of each session's comm. (I/O) state.

Anyway, I'm glad that websocket works for you.

It does
require that you write your process to NOT "STOP RUN". It's been around
since the mid 90's, and also requires building (configure/make/install),
and some additional httpd configuration, installation of,
and so on....... much work to do! Maybe wedsocket is simpler, and common
in todays www. Thank you so much for the info.
