Do not read too much from it. The sentence is correct, please remember though that CGI Executes on the Servers Side
and this is STDIN of the Server Side thread, created and executed by Apache TS Application Server.

Just like any other CGI, GET Information is passed in the Environment 'QUERY_STRING' Variable and POST Information is
provided via Process' STDIN. In the latter case the length of the input is provided by 'CONTENT_LENGTH' Environment
variable.

Trust me, if you are coding CGI Task you do not want to start that low (you can of course - if you know what
you are doing). From within your CGI code Posted information is accessible via CGI or TeamSite::CGI_lite
Packages, both DevNet and TeamSite® Workflow Developer’s Guide have samples..
