      To reproduce:

       # unzip the server and start ./bin/standalone
       # start the cli client ./bin/jboss-cli.sh -c
       # setup the server and deploy deployment

      /subsystem=undertow/server=default-server/host=default-host/setting=access-log:add()
/subsystem=undertow/configuration=filter/gzip=gzip-filter:add()
/subsystem=undertow/server=default-server/host=default-host/filter-ref=gzip-filter:add()

deploy simple-web.war

       # start e.g. Wireshark to see the data traffic and perform curl request against the server:

      curl -H "Accept-Encoding: gzip" http://localhost:8080/simple-web/dummy-text.html --compressed

      There is a change in server behavior after this commit. It was introduced as a fix for UNDERTOW-2243.

      Before this commit, a testing scenario for gzip filter received data with the regular "fixed-length" response from the server (Content-Length) header used (see gzip-content-length.png and gzip-content-length.pcapng). After this commit, server decides to use chunked transfer for the data without using the Content-Length header (see gzip-chunked.png and gzip-chunked.pcapng). Technically this may not be any problem, but this change means more ping-pongs between server and client.
