By tag jquery-validation-engine I assume you're using jquery jquery.validationEngine.js plank, if that's true then first download the files at link (if necessary).

If the field is required: 

class="validate[required,custom[url]] text-input"

If the field is optional: 

class="validate[custom[url]] text-input"

Use should look something like: 

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="../css/validationEngine.jquery.css" type="text/css"/>
    <script src="../js/jquery-1.8.2.min.js" type="text/javascript"></script>
    <script src="../js/languages/jquery.validationEngine-pt-br.js" type="text/javascript"></script>
    <script src="../js/jquery.validationEngine.js" type="text/javascript"></script>
    <script>
    jQuery(document).ready(function(){
        jQuery("#meuFormulario").validationEngine();
    });
    </script>
</head>
<body>

    <form id="meuFormulario" class="formular" method="post">
        <label>
            <span>Field is optional : </span>
            <input value="" class="validate[custom[url]] text-input" type="text" name="optional" id="optional" />
        </label>
        <button>Enviar</button>
    </form>
</body>
</html>

Now if you really want to check if the link is from Steam, you can create your own validator, for example in HTML do something like: 

 <input value="" class="validate[required,funcCall[checarLinkSteam]] text-input" type="text" id="linksteam" name="linksteam" />

If the link is from a profile you can validate with regex like this (in this example you accept id and url with profile ): 

/^http://steamcommunity\.com/(id|profile)/([^/]+)$/.test(...)

If it is a link of any of the steam you can validate like this: 

/^http://steamcommunity\.com/([^/]+)$/.test(...)

In the script add: 

    <script>
    jQuery(document).ready(function(){
        jQuery("#meuFormulario").validationEngine();
    });

    function checarLinkSteam(field, rules, i, options){

        //Valida se é um profile (o ! na frente é para negação, basico uso de IFs)
        if (!/^http://steamcommunity\.com/(id|profile)/([^/]+)$/.test(field.val())) {
            return options.allrules.validate2fields.alertText;
        }
    }
    </script>
</head>

Based on examples: link

Specifically the field being a steam link does not exist anything that I know, but at the beginning you can use , to specifically check if the user is inputting a link, you can later do a Checking the typed string using some javascript function, here are some solutions. How can I check if a string does it contain another in Javascript?
