<PRE>Headers are one thing but it'd be useful to know the request line itself.

</I>>>><i> Hi guys,
</I>>>><i>
</I>>>><i> So, I was getting a CORS issue when connecting to my Bullet impl, which I have since fixed. I am now able to use these from many machines from many locations. However, I have found some machines to be getting a 505 error when making a POST request to the Cowboy instance:

</I>>>><i> date:Mon, 22 Apr 2013 12:22:50 GMT
</I>>>><i> server:Cowboy
</I>>>><i>
</I>>>><i> To get around the CORS issue, I set up an onrequest hook, which points to the function:
</I>>>><i>
</I>>>><i> set_request_cors(Req) ->
</I>>>><i> Req2 = cowboy_req:set_resp_header(<<"Access-Control-Allow-Methods">>, <<"GET, POST, OPTIONS">>, Req),
</I>>>><i> Req3 = cowboy_req:set_resp_header(<<"Access-Control-Allow-Headers">>, <<"Content-Type, X-Requested-With, Origin, Method">>, Req2),
</I>>>><i> cowboy_req:set_resp_header(<<"Access-Control-Allow-Origin">>, <<"*">>, Req3).
</I>>>><i>
</I>>>><i> I'm afraid I don't have any more info, but this issue is completely eluding me.
