Send a series of lines with the same info over an input channel, as was done 3 years later for FastCGI. Since CGI uses stdout for the finished product, it could have used stdin for the input. Using a serial channel does put more burden on the page server to parse the input. But is allows it to be on a different machine. -- Terry Jan Reedy
