XSS之xssprotect

1 Cannot forward a response that is already committed
http://blog.csdn.net/quechao123/article/details/6256653
2 Cannot forward after response has been committed转发
http://heisetoufa.iteye.com/blog/227195
3 java.lang.IllegalStateException:Cannot forward after response has been committed
http://www.myexception.cn/java%20exception/1223.html
报错如下:
java.lang.IllegalStateException: Cannot forward a response that is already committed.
java.lang.IllegalStateException: Cannot forward a response that is already committed
at weblogic.servlet.internal.RequestDispatcherImpl.forward(RequestDispatcherImpl.java:97)
at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:225) Truncated. see log file for complete stacktrace
错误原因:
1.在forwar之前,response就已经commit到浏览器端了。
导致response commit的原因包括:forward, redirect, flushBuffer
2.前两个原因都是指在forward之前就已经进行了页面跳转动作(forward, redirect)。
3 Response.sendRedirect();后没有加return语句.
解决方法
1 增大缓冲区大小:
2 加上return null
总结:其实主要的是程序的问题,仔细检查逻辑是否正确

servlet.getServletContext().getRequestDispatcher("/DateUpdatePage.do").forward(request, response);
response既然已经commit 在此处再使用response会报空指针异常。
