HAProxy on PFSense simplification

[ninjamonkey198206]

@dani-garcia @RichardMawdsley I believe the example config can be simplified slightly. HAProxy does support multiple ACLs in the Actions section of a front end, so I typically use a primary ACL of "Host matches" FQDN with other ACLs as necessary.

In the actions, simply enter the primary "Host matches" ACL, a space, and the next ACL. Several can be used, each just needs to be separated by a space.

I'll post the equivalent CLI variant shortly.
