Compression websocket messages about atmosphere HOT 8 OPEN

@repbl444 can you share a simple test cas on Github?

from atmosphere.

I am a newby in atmosphere so maybe I do not understand something. I thought that atmosphere has something to compress messages through websocket , I just should put a flag (true) . By this flag I mean to activate for example some extensions. And JSR356 looked like the one. For me it is necessary to run it on glassfish5(payara5) and I did there some configuration like
<protocols> <protocol name="http-listener-1"> <http comet-support-enabled="true" compressable-mime-type="application/javascript,application/json" compression-min-size-bytes="1024" max-connections="250" default-virtual-server="server" compression="on"> <file-cache></file-cache> </http> <ssl></ssl> </protocol> <protocol name="http-listener-2" security-enabled="true"> <http comet-support-enabled="true" compressable-mime-type="application/javascript,application/json" compression-min-size-bytes="1024" max-connections="250" default-virtual-server="server" compression="on"> <file-cache></file-cache> </http> <ssl classname="com.sun.enterprise.security.ssl.GlassfishSSLImpl" cert-nickname="s1as"></ssl> </protocol> <protocol name="admin-listener"> <http encoded-slash-enabled="true" max-connections="250" default-virtual-server="__asadmin"> <file-cache></file-cache> </http> </protocol> </protocols>
maybe just for streaming transport I thought it should work okay
https://github.com/repbl444/atmosphere-samples/tree/master/samples/meteor-chat
I did a commit in the fork. There I have some changes in web.xml
I just didn't find an article how to activate compression with atmosphere websockets/streaming.
Maybe I did something wrong and I need some advice, thank you in advance

I also add a gzip compression to the application with Spring MVC https://github.com/repbl444/SpringMVCtestCompression
compressable-mime-type="application/javascript,application/json" compression-min-size-bytes="1024" compression="on"
in payara5 in domain.xml like I did for the meteor-chat. After enabling gzip compression I can find some info, that it works
and see that the size of the messages is really decreased.

As I understand right for websocket we also can use headers like Content-Encoding or Sec-Websocket-Extensions
with the value permessage-deflate or gzip. But I did get how to turn them on.
But for now I have this Response from the server side

and this request

Could you give me an advice please?
Can I turn on a compression for websocket messages with just payara5 configuration or something with atmosphere or maybe both?

@repbl444 Salut. I don't have time right now to take a look, but I suspect you need to use Nettosphere if you want to use compression with Atmosphere. I haven't implemented the support for other server. Sorry! I will be happy to integrate your work if you take the Atmosphere code and implement it.

Got it, thank you

Can you give me some hints please which classes/configurations needs to be changed in atmosphere to support compression with glassfish? Thanks in advance.

@repbl444 Just write an AtmosphereInterceptor and check when the transport is websocket, compress it using an open source library.

Hello, thank you for hints. Now I use atmosphere http streaming instead of websocket with a gzip compression. It needs only a configuration in a server.
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" compression="on" compressionMinSize="1024" compressableMimeType="text/html,text/plain,text/css,application/javascript,application/json" />
This is only thing I need to add for tomcat9 to have a compressed messages from a scheduler I have in my example
https://github.com/repbl444/spring-atmosphere-chat-example. But I need to run it in payara5/glassfish5. It works correctly in payara only when without compression. When in domain.xml I turn the compression on, the streaming connection can not be created.
<protocol name="http-listener-1"> <http comet-support-enabled="true" compressable-mime-type="text/html,text/plain,text/css,application/javascript,application/json" compression-min-size-bytes="128" max-connections="250" default-virtual-server="server"> <file-cache></file-cache> </http> <ssl></ssl> </protocol>
Configuration for domain.xml

Glassfish says that it supports the compression when the version of http/1.1 and I have the same

Maybe it is a bug or maybe I missed something. Could you give your opinion about that please?
