[s0i37]

What is the current behavior?

#1293
#1476

Uniq flag --filter-thresold doesn't work correct:

Small web-app for testing it:

<?php
switch(rand(0,10))
{
        case 1:
                http_response_code(200);
                echo 'ok';
                break;
        case 2:
                http_response_code(401);
                echo 'not auth';
                break;
        case 3:
                http_response_code(403);
                echo 'forbidden';
                break;
        case 4:
                http_response_code(500);
                echo 'error';
                break;
        default:
                http_response_code(404);
                echo 'not found';
                break;
}
?>
