I'm using 2 Apache with two separate ports in same machine. It means Apache 1.3 with 8001 and Apache 2.2 with 8002 Port. I used SSL (self-signed) too. I used same user name and password for both. Now I can go from https://192.168.1.1:8001/mypage.cgi to https://192.168.1.1:8002/secondpage.php easily. But it ask me username and password again. When you open https://192.168.1.1:8001/mypage.cgi, it asked username and password, and when you click on a link and go to https://192.168.1.1:8002/secondpage.php, it asked username and password again. I want to ask one time authentication info not two times.
