explicit specification of encryption in each request

[anshnd]

I need to make two separate session encryptions within the same location and they shouldn't share the same key. I tried in vain to add encryption key as an optional additional parameter to set_encrypt_session or set_decrypt_session but got stuck when I couldn't tell whether the optional parameter was specified.

As an alternative I added two new directives: set_encrypt_session_keyed $target <value> <key> set_decrypt_session_keyed $target <value> <key>
