Hi Bo,
This is a FAQ :) The 20 in the code is probabaly redundant.
================================================
About the other problem, i.e. getting data from a POST
request
within a REBOL CGI script: keep in mind that read-io is a
very-low-level read request that returns as soon as the OS
returns something. The amount of data returned is not
necessarily
what was requested. It can be less. This is not a bug, it is
by
design. If you see a limit of around 4096 bytes then this is
caused
by how the OS clusters its data. What you need to do in a
CGI
script is loop until read-io returns 0, e.g.
cgi-str: make string! 100000
while [0 < read-io system/ports/input cgi-str 100000] []

len_post: ( 20 + load system/options/cgi/content-length )
post: make string! len_post
while [0 < read-io system/ports/input post len_post ] []
do decode-cgi post
]
