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 > > If I want to access a web page and I don't know what the realm is,then what > should I write in place of realm? 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.
