=======================
httpClient.setRedirectStrategy(new DefaultRedirectStrategy() {
@Override
protected URI createLocationURI(String location) throws
ProtocolException {
try {
int index = location.indexOf("?");
if (index != -1) {
String url = location.substring(0, index + 1);
String params = location.substring(index + 1);
StringBuilder sb = new StringBuilder(url);
String[] pairs = params.split("&");
if (pairs != null && pairs.length > 0) {
for (String pair : pairs) {
String[] param = pair.split("=", 2);
if (param != null && param.length == 2) {
sb.append(param[0]).append("=").append(URLEncoder.encode(param[1],
"utf-8")).append("&");
}
}
location = sb.toString();
} else if (params.length() > 0) {
String[] param = params.split("=", 2);
sb.append(param[0]).append("=").append(URLEncoder.encode(param[1], "utf-8"));
location = sb.toString();
}
}
} catch (UnsupportedEncodingException e) {
logger.error(e.getMessage(), e);
