URL Redirect Switch not detecting on host for base domain

Expanding on from DannisJann’s answer, I recommend using

getfield

around the

HTTP::host

command to remove any trailing port e.g.

curl -iv http://domain.com:80/

should still match in the switch statement.

Also you do not need to use the

pool

command as you have not overwritten the Virtual Server configured pool earlier in the iRule.

If you have used the

pool

command in an earlier iRule then you may want to put your pool selection back in but recommend using

pool [LB::server pool]

instead of the pool by name.

when HTTP_REQUEST {
    switch [string tolower [getfield [HTTP::host] : 1]] {
        "domain.com" -
        "www.domain.com" -
        "uat.domain.com" {
            HTTP::respond 301 Location "https://[HTTP::host][HTTP::uri]"
        }
        default {
            return
        }
    }
}
