I don't believe the communication between apache and tomcat is secured by default. Is there a way to have it send the information in a secure way. I do not presume to know the sensitivity of the data passing between your webserver and your application server, not the physical topology of your network, nor the real possibility of the data being compromised, nor the real capabilities of your servers. But if you were to make an SSL connection between the front-end and the back-end, you would more than double the encryption overhead. Supposedly, the clients already connect to Apache via HTTPS, and Apache has to decrypt the data on the way in, and encrypt it on the way out to/from the client. That will remain the case anyway. But if Apache has to communicate with the Tomcat back-end via SSL, it will need to do the same encryption/decryption for all the data a second time, and Tomcat at its end also. That is true no matter which method you would use, tunnel or HTTPS proxy. It may be a necessity, and it may be affordable, but it should not be a decision taken lightly thinking it is free of consequences. A crossover cable is less exciting, but may be much cheaper. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

What group is responsible for the Tomcat AJP protocol? Is there a way to request a feature to add SSL encryption to the protocol?

If you really needed to do this, you could use an SSH tunnel however. If you really needed to and the physical constraints allow it, you could also link your Apache with the back-end Tomcat with a dedicated LAN, and avoid the overhead of SSL. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
