Set header, add header, but how do I delete one?

Pretty simple, deleting headers, how do I do this?

You can do it as follows:

self.request.headers.pop("headers_key")

Currently the only way to delete an outgoing header is with
RequestHandler.clear(), which resets all headers and buffered output.

But sets some again.

def clear(self): """Resets all headers and content for this response.""" self._headers = httputil.HTTPHeaders({ "Server": "TornadoServer/%s" % tornado.version, "Content-Type": "text/html; charset=UTF-8", "Date": httputil.format_timestamp(time.time()), 

})

 There's a new clear_header method, so use that:

tornado.web.RequestHandler.clear(self)

self.set_header('X-Accel-Redirect', redirect_location)

self.clear_header('Content-Type')

( if in this case you need to not have the Content-Type set as the .clear method sets content-type to text/html )
