> When using ResourceStreamRequestTarget + FileResourceStream to send a file <2G, the resulting Content-Length in the header is a large negative value. This is due to a cast between a long and an int.
> In wicket, all methods dealing with content-length use longs, but the servlet api HttpServletResponse takes in an int, so WebResponse casts the long into an int which causes the problem.
> The simple work around is to check for >2G lengths and use the addHeader method instead of setContentLength.
> Attached is an extended WebResponse that fixes the problem.  This should probably be applied to WebResponse.
