Below is code to set the URL filter. Needs to be modified to:

• Not throw an exception when the URL is invalid
• Do not replace the domain filter if it is not empty
• Set a filter of * if multiple domains exist

function getDomain (thestring) {
    //simple function that matches the beginning of a URL
    //in a string and then returns the domain.
    var urlpattern = new RegExp("(http|ftp|https)://(.*?)(/.*)?$");
    var parsedurl = thestring.match(urlpattern);

    if( parsedurl && parsedurl.length >= 2){
        return parsedurl[2];
    }
    else{
        return null;
    }
}

$("input[name=Domain]").focus( function() {
    urls = cp1.getCode();

    url = urls.split("\n")[0];
    url = getDomain(url);
    $("input[name=Domain]").val("*" + url + "*");
});
