The
main()
methodfirstcreatesan
HTTPServer
instancethatdescribesanHTTP
server connected to port 9901 of the local host. This method next creates the
/Tem-

context, and returns the resulting
HttpContext
subclass object.
Continuing, the abstract
com.sun.net.httpserver.BasicAuthenticator
class is anonymously
subclassed to describe a server side implementation of HTTP basic authentication; its
boolean checkCredentials(String username, String password)
methodiscalledtoverifythegivennameandpasswordinthecontextofthebasicau-
thenticator's realm. Thismethodreturnstrueforvalidcredentials, andfalsewhenthey

After passing the
