Comments on: CGI requires content-length
I've noticed that various Rebol CGI website scripts hang. Apparently, HTTP POST on newer servers (or clients actually) keeps the socket open in such a way that the standard read-cgi function hangs.
The fix I use in newer scripts is to use the CGI content-length field to terminate the read.
If you have insights into this problem, please comment. I'd like to fix read-cgi in the next release.

You can disable persistent connections with:
Connection: close
added to the HTTP headers. See:
https://en.wikipedia.org/wiki/HTTP_persistent_connection
I guess servers now default to HTTP/1.1 at least and assume CGI scripts can handle that (though... it seems strange that the would on good old CGI... I wonder if there's something else going on).
Note also that you can support keep alive connections on scripts even if you don't know the output Content-Length in advance using the chunked transfer encoding:

The most essential output for a CGI program is a straightforward report in either plain text or HTML, which the browser shows as it would any document on the Web. Visit https://www.emailcustomercareservice.com/blog/tag/oops-a-server-error-occurred-and-your-email-was-not-sent-007/ | Rohit
