Hello!
My maxscale version is 2.3.11-1.x86_64

When I use direct connection, like this
mysql -h <SERVER_IP> -u <DB> -P<PORT> -p -C -e "\s"
I have in my output:

Protocol:               Compressed

When I try it through maxscale, I can't see "Compressed" in my output. How can I get compression with maxscale?

I have problem like this link on my php application:
https://jira.mariadb.org/browse/MXS-702

when I try use compression with mysqli code from description -> I get freez
when I try use PDO with strace:

sendto(3, "\r\0\0\0\0\0\0\t\0\0\0\3SELECT 1", 20, MSG_DONTWAIT, NULL, 0) = 20

poll([{fd=3, events=POLLIN|POLLERR|POLLHUP}], 1, 1471228928) = 1 ([{fd=3, revents=POLLIN}])

recvfrom(3, "\30\0\0\1\377\27\4#08S01Unknown command", 78, MSG_DONTWAIT, NULL, NULL) = 28

poll([{fd=3, events=POLLIN|POLLERR|POLLHUP}], 1, 1471228928^Cstrace: Process 7937 detached

I think PDO use mysqlnd, but I can't understand why compression not work with native mysql client.

Can you explain for me this sentance:

Compression is not included in the server handshake.
