Tomcat in our application is considered back-and side and additionaly we have apache that fronting tomcat server as a reverse proxy and redirect requests to appropriate tomcat instance.
Now we need to set up HTTPS connection between apache proxy and tomcat for specific urls(Login, etc..). Tomcat documentation says that it's possible to achieve this with additional <Connector> within server.xml config.
In order to set up https over login page existing configuration with AJP protocol was replaced with the following:
ProxyPass /app/login/ https://127.0.0.1:6666/app/login/
All other urls specified like below:
ProxyPass /app/anyotherurl/ ajp://127.0.0.1:5555/app/anyotherurl/
With configuration below we expect that secure data (login/password) for login page will be encrypted and all other page will remain unchanged.
After the login apache should use normal ajp protocol because there is no sensetive information any more to protect. But it's not what actually happen in our case because for some reason apache is redirecting us to host specified in ProxyPass, namely to localhost. This could happen due to the fact that our application while executing login logic on tomcat has two consecutive redirects.
We've tried to set ProxyPreserveHost on within virtual host to fix situation mentioned above, but we are not sure whether it is secure option and this one won't break another pages as well as we are not sure how it will work if tomcat will be located on other machine.
It would be good to know any other solution how such stuff can be applied internally for specific pages.
