now i have successfully set the 'nginx.conf ' like this:

29 auth_basic "LTP Web Service";
30 auth_basic_user_file ltpasswd;

and when visit the web site, it will pop a box ask for username and pwd. here is problem:

i want to communicate with the server by C++/JAVA or some other languages and don't know how to put my username and pwd to the server.
shall i add Authorization Option to the http header or write something in cookie?
