Configuration options for Netty

How to configure Netty parameters in play

Ref: https://www.playframework.com/documentation/2.3.4/ProductionConfiguration

The following HTTP protocol options are supported:

• http.netty.maxInitialLineLength The maximum length for the initial line of an HTTP request, defaults to 4096
• http.netty.maxHeaderSize The maximum size for the entire HTTP header, defaults to 8192
• http.netty.maxChunkSize The maximum size that Netty will buffer body chunks before splitting them, defaults to 8192

Play also allows configuring the full list of TCP socket options that Netty supports, by prefixing them with http.netty.option. Note that socket options that should be applied to sockets of accepted connections should have an additional child prefix before the option. Here are some common ones:

• http.netty.option.child.keepAlive Set to true/false to turn on/off TCP keep alive
• http.netty.option.backlog Configure the maximum size for queued incoming connections
