[REBOL] Re: html post

Hi Andrew,

Again, I seem to recall that there was a problem with relying on content-length, but if it is working for you then hey who am I to disagree! :^) Here is an excerpt from a script of mine that process standard input for the NoteTab editor. So it is not CGI, but very related. The relevent bit is the while loop condition that checks for the result of READ-IO which I think is the number of bytes read. I've no idea how this would react in a CGI environment, maybe if you have a webserver on your personal machine you could try it? You could probaby ignore my character manipulations (they are probably only relevent to my editor usage). standard-input: function [ "Returns a string that comes from standard input." ; May not be suitable for large input streams. ] [buf-size inp inp-buffer log] [ buf-size: 30000 inp-buffer: make string! buf-size inp: make string! buf-size while [ clear inp-buffer 0 < read-io system/ports/input inp-buffer buf-size ] [ replace/all inp-buffer "^M" "" ; Handles CR on windows systems. append inp inp-buffer ] inp if all [ 0 < length? inp equal? last inp to-char 26 ] [ remove/part at inp length? inp 1 ] inp ] Regards, Brett.
