Hi folks -

I've been experimenting with using Python to access the user profiles API. I kept getting an "HTTP 406" error and eventually figured out that I wasn't sending an "Accept" header to the /v1/user/guid/profile endpoint. Once I added an "Accept: *" header everything just worked.

The HTTP spec says that the accept header is optional: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

"If no Accept header field is present, then it is assumed that the client accepts all media types. If an Accept header field is present, and if the server cannot send a response which is acceptable according to the combined Accept field value, then the server SHOULD send a 406 (not acceptable) response."

I'm using the standard python library urllib2 to make these requests. It's likely that other people using python will run into the same problem. Can you change your server so that it does not require the Accept header?

Here's the request I sent:
