Is it true that if proxy is setup https->http then it only has to decrypt/encrypt the headers and the body is encrypted/decrypted on the backend? What ? Eh, no. If you configure your frontend with https and your backends with http, then you just told apache to NOT use SSL between mod_proxy and the backend servers. Only your frontends will do SSL handshakes in this setup. That's pretty much SSL Offloading, maybe you got that confused ?
Sorry, it was a typo of course. I mean: https->https. So if a proxy forwards https to the backend which accepts https - then would the proxy decrypt the headers only or the entire request? I am adding cookies at the proxy for stickyness so the proxy must be handling the headers. In my case http at the backend could be an option inside a trusted network. kuba --
