Java: streaming the contents of a zip file over HTTP

I have quite a lot of streaming data (> 100 MB) which I would like to place in a zip file on an http server for compression. So this zipfile contains one file.

Is it possible for a java client to be able to transfer data via http, even if it is packed into a zip file?

According to Wikipedia, ZIP files are not consistent ...

http://en.wikipedia.org/wiki/ZIP_(file_format)#Structure

If this is still possible, then how?

edit: about gzip: as I said, I use a custom java client (not a webbrowser) - is gzip available in the java-http implementation?
