Printing the called address without PATH_INFO and QUERY_STRING

[Alexander.Farber]

Hi,

this is probably somewhere in the docs, but I can't find it...
Would some kind sould please advise me, how to print the 
hostname and the called script in the error message below?

    # Extract port, user, default database from PATH_INFO
    $port  = $1 if $r->path_info() =~ /\/port=(\d+)/i;
    $owner = $1 if $r->path_info() =~ /\/owner=(\w+)/i;
    $dbase = $1 if $r->path_info() =~ /\/dbase=(bo_\w+)/i;
    $task  = $1 if $r->path_info() =~ /\/task=task(\d+)/i;
    unless ($port and $owner and $dbase and $task) {
        printf "<H2>Error: This script should be called as 
http://%s/taskit/port=1234/owner=afarber/dbase=bo_test/task=task123</H2>", 
$r->server->server_hostname();
        $r->log_error('PATH_INFO unset or wrong: ' . $r->path_info());
        goto END;
    }

Thanks
Alex
