List of usage examples for javax.servlet ServletRequest getParameterValues
public String[] getParameterValues(String name);
String objects containing all of the values the given request parameter has, or null if the parameter does not exist. From source file:com.mtgi.analytics.servlet.ServletRequestBehaviorTrackingAdapter.java
