Hi, I'm not sure what you need. You just need to log:

when HTTP_REQUEST {
    if { [HTTP::host] contains "testlab.john.com" and [HTTP::uri] starts_with "/abcdef/api/" } {
        log local0. "[substr [HTTP::uri] 7]"
        pool testlab
    }
}

or you need to strip and rewrite uri before send to a server:

when HTTP_REQUEST {
    if { [HTTP::host] contains "testlab.john.com" and [HTTP::uri] starts_with "/abcdef/api/" } {
        log local0. "[substr [HTTP::uri] 7]"
        HTTP::uri [substr [HTTP::uri] 7]
        pool testlab
    }
}

Regards.
