Config order -- when will it matter? (1 reply)

I'm working on some changes to a frontend, one of which is moving the
port 80 bind into the same frontend as port 443.

Which of the many directives that I'm using will be evaluated in order,
and which of them will take effect first no matter where they are?

Specific questions:

Will the "blockit" ACL in the config below kill a matching connection on
port 80 before the redirect to HTTPS happens, or is "redirect scheme"
handled out of order with the rest of what I've got configured?

Are the "use_backend X if" statements evaluated in order? What I'm
trying to do would require this.

Any insight is appreciated.

Thanks,
Shawn
