CP-2240 HttpException: Headers size exceeded the of '8192' bytes

@jayudey-wf reported that when trying to download a large file via the file transfer example, this error may be encountered on the server:

Unhandled exception:
HttpException: Headers size exceeded the of '8192' bytes
#0      _rootHandleUncaughtError.<anonymous closure> (dart:async/zone.dart:883)
#1      _microtaskLoop (dart:async/schedule_microtask.dart:41)
#2      _startMicrotaskLoop (dart:async/schedule_microtask.dart:50)
#3      _runPendingImmediateCallback (dart:isolate-patch/isolate_patch.dart:96)
#4      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:149)

Need to do some research on maximum header & body sizes. Need to catch this error in the server code and fail gracefully and add some documentation to the example about it.

Were you ever able to fix this issue on your end? I'm encountering the same in Angel
when proxying pub serve. I feel like it has to do with this issue:

dart-lang/sdk#28251

I don't think using a reusable buffer is the solution - that's what Angel already does, and still encounters this error.

Cheers!

@thosakwe unfortunately I haven't looked into it any further - it is only an issue with our example server and not with this package so it hasn't been a high priority.
