Hi,
I am doing the same thing with much bigger envelops.
At the server I use a Apache2 module mod_deflate that
compresses all XML using zlib before sending it back
to the client. The client-browser will decompress and
pass the XML back to your application. Most browsers
do support this server-side compression and notify the
web-server by adding an appropriate HTTP-header to
your request. So the only this you have to do is
enable compression at your web-server.
The other way around, when sending large XML envelops
to the server, you can compress the XML by converting
the XML to a ByteArray, compressing it and sending it
to the server. You will hane to set the contentType to
"application/octet-stream" or something similar. Then,
server-side I decompress it using zlib (in C++/Boost)
to get to the XML. An alternative way is to let your
web-server decompress it, but I didn't get this to
work and gave up on it.
My experience with compressing XML is very good. The
cost of decompressing/compressing does not out way the
network overhead. I timed compression in Flex with
getTimer() and it only costs a few msec for up to
500k. Small envelopes (5k) can not even be timed with
getTimer(), it shows 0 msec all the time.
Good luck,
Andrej
