Playframework: TooLongFrameException: HTTP header is larger than 8192 bytes

I'm constantly getting this error when passing URLs through.

org.jboss.netty.handler.codec.frame.TooLongFrameException: HTTP header is larger than 8192 bytes.

Is there a way to increase maxHeaderSize? I've tried -Dhttp.netty.maxHeaderSize and -Dplay.server.netty.maxHeaderSize, but neither of them do the trick even though maxInitialLineLength can be modified using either of those options.

Any help would be appreciated. Thanks!

The URL for a request is not an HTTP header, it's in the initial line, so you need to configure -Dhttp.netty.maxInitialLineLength or -Dplay.server.netty.maxInitialLineLength depending on which version of Play you're using.

[twiho]

Can someone, please, help me understand what the "initial line" is?
Edit: oh it is the initial request line I suppose, https://www.jmarshall.com/easy/http/ for anyone wondering

[wsargent]

maxInitialLineLength is the maximum length of the initial line (e.g. "GET /
HTTP/1.0" or "HTTP/1.0 200 OK") of the HTTP request or response. The URL
is part of that line.
