Prioritize Multi Site rules over Basic rules
Currently, basic rules take precedent over multi-site rules. Logically you want to go from granular to generic, so this really should work the other way around. For example, if i have a multi-site rule for sitea.com on port 443 that uses backend pool a and a basic rule that forwards everything else on 443 to pool b currently everything will go to pool b instead of the filtering action occurring.
Currently the rules are matched by order. So if you have multi-site rule first in your configuration, it would take precedence. We take the feedback on most specific rule match and will be reviewing it for release.
