No need, you can do this now. If you gzip a file and send it via post
response (sendAndLoad), the browser will decompress it for you
automatically
A possible use case: You need to load themes into your application at
runtime. Those themes potentially consist of many assets of different
type (xml, bitmap, swf, etc) and people should be able to create those
assets using their favourite tools which may or may not include flash.
In order to minimize requests to the server you could offer a way to
pack them together accompanied by a catalog xml file (think swc). Again,
users should be able to use their favourite zip tool to do that.
As FP9 supports runtime un/compressing of ByteArrays, it is
theoretically possible to let it load zip archives and uncompress the
contained files at runtime, with minimal processor load.
The problem however is that zip and zlib use different checksum methods,
you thus can't uncompress files contained in zip archives created by 3rd
party tools. You probably would have to write your own zip-like tool
that uses either FP9 or a zlib library to compress files, and use
ADLER32 checksums instead of the usual CRC-32 checksums.
Cheers,
Claus.
