--- Comment #2 from Rainer Jung <rainer.j...@kippdata.de> ---
I think he wants an optional IP config attribute per worker. That IP would be a
locally configured ip chosen by the admin. mod_jk would then bind() to that IP
before doing the connect(). One choses port 0 and sets SO_REUSEADDR. bind() is
typicaly used before accept() (server side) and not before connect() (client),
but is is allowed for the client as well and for complex systems can do
something useful. If there are multiple local IPs and/or multiple possible
interfaces and routes form the web server to the backend, you can chose from
which IP the connection from the point of view of the backend comes.

Sometimes you can work around not being able to configure that IP by setting
host routes on the web server but for that solution you need to have root
access.

I think it is a useful extension and not an exotic feature, though most people
will not have a need to use it. The few who need it really need it :)
