In source code(https://github.com/Netflix/zuul/blob/2.1/zuul-core/src/main/java/com/netflix/zuul/message/http/HttpQueryParams.java#L118), we can see get() method uses name.toLowerCase() as key, while getFirst() method uses original name.
public List get(String name)
{
return delegate.get(name.toLowerCase());
}
Suppose current url is xxx?cityId[]=1&cityId[]=2, invoke get("cityId") would cause none value which is not expected. Is there any special reason to use lower case of param key rather than original key?
