Secondary load balancing method (fallback) (1 reply)

Is it possible to configure a secondary load balancing method, something to
fall back on if the first method isn't met?

For example, if I balance on the url_param email:

balance url_param email

Can it instead balance on another url_param:

balance url_param id

Or have it balance based on source address?

I tried setting the following:

balance url_param email
balance url_param id

But it only balanced on the second one, id.

I haven't found anything saying this is possible, but I'd just like to make
sure it isn't.

Thanks.
