ok it should now correctly detect also https URLs.
Anyway this is the regular expression used to detect URL, it should be improved (there are other URLs that are not recognized here and there)
/^http(s)?\:\/\/(www\.)?[a-zA-Z0-9\-\_]+(\.[a-zA-Z0-9\-\_]+)?\.(com|net|it|info|org|eu|uk|ca|us|cl)((\/[a-zA-Z0-9\_\-\+]+)*(\/([a-zA-Z0-9\_\-\.\+]+\.(php|html|htm|asp|aspx|jsp|cgi))?)?)?(\?([a-zA-Z0-9\_\-\+\s]+\=[a-zA-Z0-9\_\-\s\+\&]+)+)?(#[a-zA-Z0-9\_\-\+\s]+)?([\s]*)?$/
We should also add all the top level domains
