I installed Apache 1.3, and Apache 2.2 on one system with different ports (444, 445). I used Apache Authentication info of 444 for both. When I want to go from port 444 to 445, Browser ask me user/password again. I want to share the session authentication info between two apache. It means, if I enter password for 444, it doesn't ask me the password again and use 444 session. I used below .htaccess for folder of second apache (444):
AuthName "Restricted"
AuthType Basic
AuthUserFile /var/Apache444/users
AuthGroupFile /etc/Apache444/groups
require group admin
