Comment (by slink):
If you want to go for the cookie based persistence, you can all of it in
vcl. Use vmod cookie, set a cookie with an id for the backend you have
chosen and then select the backend based on that cookie.
Regarding non cookie-based persistence:
If you were looking after a more stable hash director, this could help
you: https://code.uplex.de/uplex-varnish/libvmod-vslp but in your case,
VSLP won't help you. To the best of my knowledge, there is no vmod for
varnish which would implement persistent sessions as f5 does and I don't
think it would be a good idea anyway, because we would open a can of worms
regarding distribution of state within varnish clusters.
Finally, we don't use trac for enhancement request, so I'd suggest you
either put your suggestion on [[Future_VMODS]] or contract someone to
implement the feature you require.
