I have tomcat configurate to send responses compresed with gzip if the cliente send me the Accept-encoding:gzip http header.

But how allow tomcat to accept compressed request with Content-encoding: gzip header?

Thanks

There is nothing really special that you need to do in Tomcat. What you need to do is write a Servlet that accepts file uploads (multipart mime input).
