    you can try something like that

    when HTTP_REQUEST {
    if {[URI::query [HTTP::uri] bypassMaintenance] equals "true"} {
        HTTP::respond 302 Location [HTTP::path] "Set-Cookie" "bypassMaintenance=true;path=/"
    } elseif {[URI::query [HTTP::uri] bypassMaintenance] equals "false"} {
        HTTP::respond 302 Location [HTTP::path] "Set-Cookie" "bypassMaintenance=false;expires=Thu, 01-Jan-1970 00:00:01 GMT;path=/"
    } elseif {!([HTTP::cookie value bypassMaintenance] equals "true") } {
        pool maintenance
    }
}

    then in the browser, request 

    http://www.company.com/?bypassMaintenance=true
    all following requests will bypass maintenance pool. this add a cookie to bypass maintenance mode.

    to reactivate maintenance mode for this session, request 

    http://www.company.com/?bypassMaintenance=false
    . it will remove the cookie.
