Compressed data (gzip files) being sent from the server are
unzipped by the browser before being passed to Flash Player -
therefore there is no need to write separate action script classes
to deal with the data.
I am getting conflicting reports from other developers saying
that the Flash player communicates directly with data coming from
the server with no stop at the browser level. According to them,
you must write actionscript classes to decompress the data.
