Hello!

Why does this code print output when I run it?
    - It only happens when the HTTP response Code is == 405
    - 173.194.69.94 is a Google Server for testing
    - Are there any default callbacks which make this output?

CODE:

OUTPUT:

http://pastebin.com/AkA3Fvw1 (Basically a HTML error page)

There must be a default onReceive that is writing that to stdout. 
If I add this line just before the perform() call the output is 
not generated:

http.onReceive = (ubyte[] data) { /+ drop +/ return data.length; 
};

I just had a quick look an this is not caused by the D interface. It's
the default behavior of libcurl if no explicit callback is set.

If desired we could add some code to the wrapper's initialize function
to automatically set this callback to a dummy function, but silently
dropping the data doesn't sound much better to me.

-------------
Set this option to NULL to get the internal default function. The
internal default function will write the data to the FILE * given with
CURLOPT_WRITEDATA.
-------------
http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPT_WRITEFUNCTION

-------------
The internal CURLOPT_WRITEFUNCTION will write the data to the FILE *
given with this option, or to stdout if this option hasn't been set.
