Don't know if this is of anyhelp but anyways... I think Tim is trying to do server push? Along that route (not done it before reading this thread) I've some marginal success with the script below in Netscape. That is netscape replaces the entity, but IE just returns all the sections. Maybe IE does not understand x-mixed-replace ? Anyway the problem with this script is that it needs to flush the OUTPUT port just prior to the wait but doesn't and I don't know how to do that. Someone else help?! :^) To include the image it will need to be written to the port as binary unless there is an option to encode it as base64 (which would need extra headers and using enbase). If you change the mode of the port to binary (again how?) you need to ensure that the "normal" text lines and headers end in CRLF (the script below relies on REBOL outputing the CRLF as a line ending).
