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.

-------------
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.
