String getUrl(String url, String oldFormat) {
Pattern urlRegex;

if ("false".equals(oldFormat)) {
urlRegex = Pattern.compile("(https?://[^/]*(/[^=]*/)*)(.*)");
} else {
urlRegex = Pattern.compile("https?://[^?]*");
}

Matcher urlTmp = urlRegex.matcher(url);
if (!urlTmp.find()) {
return "";
}
if ("false".equals(oldFormat)) {
return urlTmp.group(1);
}
return urlTmp.group();
}

Map<String, String> getQueryParams(String url, String oldFormat) {
Pattern splitRegex;
if ("false".equals(oldFormat)) {
splitRegex = Pattern.compile("(/)([^/]+)");
} else {
splitRegex = Pattern.compile("(\\?|&)([^(&|\\?)]+)");
}

Matcher splitTmp = splitRegex.matcher(url);

Map<String, String> retval = new HashMap<String, String>();
int j = 0;
Pattern paramRegex;
if (oldFormat == "false") {
paramRegex = Pattern.compile("[^(/|&|=)]+=[^(/|&)]*");
} else {
paramRegex = Pattern.compile("[^(&|=)]+=[^&]*");
}

for (int i = 0; i < splitTmp.groupCount(); i++) {
Matcher paramTmp = paramRegex.matcher(splitTmp.group(i));
if (paramTmp.find()) {
String[] splitParam = paramTmp.group().split("=");
retval.put(splitParam[0], splitParam[1]);
