I doubt there's a config setting to change this within Umbraco. You could write a HTTPHandler that intercepts this request and responds appropriately, maybe by just stripping this parameter.

This would disable this functionality completely but it's not core functionality as it only allows the user to jump to a specific page in the back office.

Thanks for your response Chris,

I opted for adding a piece of JS in login.aspx

<script type="text/javascript">  
            $(function() {
                function getUrlVar(requestedKey) {
                    var vars = [], hash;
                    var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');

                    for (var i = 0; i < hashes.length; i++) {
                        hash = hashes[i].split('=');
                        vars.push(hash[0]);
                        vars[hash[0]] = hash[1];
                    }
                    if (typeof requestedKey == 'undefined') {
                        return vars;
                    } else {
                        return vars[requestedKey];
                    }
                }

                if ($("form#Form1").length > 0) {
                    if (getUrlVar("redir") != "/umbraco/default.aspx") {
                        var currentUrl = window.location.href;
                        var redirPos = currentUrl.indexOf("redir");

                        window.location.href = currentUrl.substr(0, redirPos) + "redir=/umbraco/default.aspx";
                    }
                }

            });
        </script>

is working on a reply...
