PlayFramework 2.2.6: Advanced HTTP server configuration maxInitialLineLength

We are trying to send GET and POST requests with a length greater than 4096 bytes to our REST API implemented with Playframework 2.2.6.

After a long google research we tried nearly everything and the solution seems to be passing the following two arguments when starting our server via play. We receive no error message about wrong parameters but when we send a large request to the api we still receive the error

TooLongFrameException: An HTTP line is larger than 4096 Bytes

We are running the server by the following command

<PathToPlay>\play-2.2.6\play.bat -org.jboss.netty.maxHeaderSize:102400 -org.jboss.netty.maxInitialLineLength:102400 run

First of all your path to start your application seems off. When you create a new play application a play.bat or activator.bat file is automatically created in your project root folder. So no need to call a specific play installation runtime outside your project folder.

The parameters for setting the max body and header length can be found in the play documentation.

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

Development Mode

To start your application in development mode call

/path/to/project/play run -Dhttp.netty.maxInitialLineLength=102400 -Dhttp.netty.maxHeaderSize=102400

If you've used Activator to create your project replace play with activator.

Production mode

After you've published your application for production with play dist you can set the parameters by calling

/path/to/publishedApp/bin/<nameOfApp> -Dhttp.netty.maxInitialLineLength=102400 -Dhttp.netty.maxHeaderSize=102400
