MarkPreservedException is thrown by MegInputStream.read() whenever a read is attempted on a marked, preserved stream and the read would exceed the readlimit supplied to mark(). The mark is left intact. This is useful when you want to mark a stream so you can reject a request later, but you don't have direct control over how many bytes are read from the stream. If too many bytes are read, the mark will become invalid and you won't be able to reject the request anymore. Here is an example:

 void handleRequest(RequestEvent e) throws RequestRejectedException {
   MegInputStream in = e.getMegInputStream();
   MegOutputStream out = e.getMegOutputStream();
   HtmlEditor ed = new HtmlEditor(in, out);
