I'm not sure I follow this. Are you referring to "mchttpd", the
MetaCard HTTP server, or something else? I think probably the latter
because you use mchttpd *instead* of Apache, not with it.

This only reads until there's no more to read *at that time*, not
until the process at the other end of the pipe has finished writing.
You'll need to either execute this command repeatedly until you get
the amount of data you're expecting, or use "read until eof" instead.

The actual buffer size depends on the version of UNIX and even on what
type of descriptor is being written to and what the two ends are
connected to. And the amount you'll get in a given "read until empty"
also depends on CPU scheduling and how the process on the other end
wrote it out. But none of this should matter if you do the reads
correctly.

Again, you lost me here. There's no reason to upload a file through a
CGI, and in fact this would be an inefficient way to do it (i.e., you
should use "PUT" instead of "POST".) Second, parameters come in as
environment variables ($1, $2, etc.), not via stdin on UNIX systems.
