Realm is set by the host. It is usually displayed in the
login dialog in
a browser, it will look like a site name.
The realm is in the headers received back from the server.
For example:
$ curl -I http://xxx.com/
HTTP/1.1 401 Authorization Required
Date: Wed, 11 Apr 2007 01:39:47 GMT
Server: Apache/2.0.52 (Red Hat) mod_python/3.2.8
Python/2.4.4
WWW-Authenticate: Basic realm="xxxx"
Content-Type: text/html; charset=iso-8859-1
Vary: Accept-Encoding,User-Agent

I think you can instantiate the HTTPBasicAuthHandler with an
instance of
HTTPPasswordMgrWithDefaultRealm. Then pass None as the realm
and it will
be used as the default.
