Logging of HttpEntities truncated to 500 characters

[ilca...@gmail.com]

We have had to create our own logging directives to use with spray routing and spray client because the provided ones use HttpEntity.toString which truncates the body to 500 characters, although a perfectly simple thing to do I have to wonder if this was intended considering that it reduces the value of what is provided on routing.DebuggingDirectives, httpx.RequestBuilding and httpx.ResponseTransformation

Thanks
