``http_auth_domain`` spider attribute to the domain which requires this
authentication (its subdomains will be also handled in the same way).
You can set ``http_auth_domain`` to ``None`` to enable the
authentication for all requests but usually this is not needed.
authentication for all requests but you risk leaking your authentication
credentials to unrelated domains.
.. warning::
In the previous Scrapy versions HttpAuthMiddleware sent the
authentication data with all requests, which is a security problem if
the spider makes requests to several different domains. Currently if
the ``http_auth_domain`` attribute is not set, the middleware will use
the domain of the first request, which will work for some spider but
not for others. In the future the middleware will produce an error
instead.
