    • PERMESSAGE_DEFLATE_DISABLE

      public static final String PERMESSAGE_DEFLATE_DISABLE
      System property key which may be used to disable the websocket's support of the 'permessage-deflate' extension, a value generally provided by modern browsers as part of the HttpHeader.SEC_WEBSOCKET_EXTENSIONS header. Setting a system property value of 'true' will remove support and may enable proxy/firewall support in systems lacking support compressed-frame forwarding, such as some versions of Microsoft IIS ARR based rewriting proxy servers.
