Long payloads of requests get truncated

[thomas-huegel]

Describe the bug
On a POST request with a long payload, only the beginning of it gets received.
On some cases the logged body is even empty!

To Reproduce

1. Create a Lorem Ipsum text file of around 6000 characters.
2. Launch the server.
3. Request to it via curl :

curl localhost:8080 -X POST -d '@lorem.txt' -H "Content-Type: application/x-www-form-urlencoded"

4. Look at what Printer() logs as the request's body.

Expected behavior
The entire payload should be handled.
