Set limit on response size for as_str handler

[parsa]

Hi folks,

I'm willing to use Dispatch in a sandboxed environment, where among all limitations, I need to set a limit on how large the response string can be. How can this be achieved in Dispatch? Thanks in advance.

Sure, you can consume the stream/reader/scala.io.Source to build up a
stream of whatever maximum size you want. The String methods are just
doing this:

     request >~ { so => so.mkString }

Where so is a scala.io.Source. Source works line by line so if you are
concerned about very long lines you may want to work with lower level
java stream or reader. For reader,

     request >>~ { reader => [make as big of a string as you want here] }

and that value will be returned. Sources here:
