         * When the request body is multipart/form-data, both the parts and the query string count towards
         * maxParameterCount. If parseParts() is called before getParameterXXX() then the parts will be parsed before
         * the query string. Otherwise, the query string will be parsed first.
         *
         * maxParameterCount must be respected regardless of which is parsed first.
         *
         * maxParameterCount is reset from the Connector at the start of every request.
         *
         * If parts are parsed first, non-file parts will be added to the parameter map and any files will reduce
         * maxParameterCount by 1 so that when the query string is parsed the difference between the size of the
         * parameter map and maxParameterCount will be the original maxParameterCount less the number of parts. i.e. the
         * maxParameterCount applied to the query string will be the original maxParameterCount less the number of
         * parts.
         *
         * If the query string is parsed first, all parameters will be added to the parameter map and, ignoring
         * maxPartCount, the part limit will be set to the original maxParameterCount less the size of the parameter
         * map. i.e. the maxParameterCount applied to the parts will be the original maxParameterCount less the number
         * of query parameters.
