39 * PostBigRequest plugin

41 * If you reach the url/header length limit of your servlet container your queries will fail.
42 * You can increase the limit in the servlet container, but if that's not possible this plugin can automatically
43 * convert big GET requests into POST requests. A POST request (usually) has a much higher limit.
44 *
45 * The default maximum querystring length is 1024. This doesn't include the base url or headers.
46 * For most servlet setups this limit leaves enough room for that extra data. Adjust the limit if needed.
