The HttpServletRequest has the following methods:
getRequestURL()
- returns the part of the full URL before query string separator charactergetQueryString()
- returns the part of the full URL after query string separator character
So, to get the full URL, just do:
public static String getFullURL(HttpServletRequest request) {
StringBuffer requestURL = request.getRequestURL();
String queryString = request.getQueryString();
if (queryString == null) {
return requestURL.toString();
} else {
return requestURL.append('?').append(queryString).toString();
}
}
