Hi,

I've ran into an issue while querying osrm-routed with latest master build (using boost::beast) using Python Requests library.

It seems the Content-Encoding: deflate has a bug, strangely enough it also seems it is the default encoding of Python Requests library.

requests.get(osrm_url) requests.get(osrm_url, headers={"Accept-Encoding":"deflate"}) 

cause an error, specifically

ContentDecodingError: ('Received response with content-encoding: deflate, but failed to decode it.', error('Error -3 while decompressing data: invalid block type')) 

while

requests.get(osrm_url, headers={"Accept-Encoding":""}) requests.get(osrm_url, headers={"Accept-Encoding":"gzip"}) 

successfully respond with http 200.

Could it be that

is encoding it wrong?
