This section covers how to set up the Query String Handling mode (QSHMode).
By default, resources are cached using their complete URL, including the query string. Because elements of the query string can be unique for each user, the result can be frequent cache misses. QSHMode allows the removal of the query string or portions of the query string from the cache key.
Currently, the API only allows suppressing the full query string, by setting the type attribute to the value "string". The action attribute determines if the query string is included in the cache key ("honor") or ignored ("ignore").
