  - PERMESSAGE_DEFLATE_DISABLE
```
public static final java.lang.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.
