302 Moved Temporarily和302 Found有什么区别？

Question

同样是302跳转，我看有时候是302 Moved Temporarily，有时候是302 Found，这两个有啥区别呢？

Answer 1

二者在不同HTTP协议下的状态信息不同。

在HTTP/1.0 302 状态为 Moved Temporarily

The requested resource resides temporarily under a different URL. Since the redirection may be altered on occasion, the client should continue to use the Request-URI for future requests.

在HTTP/1.1 302 状态为 Found

The requested resource resides temporarily under a different URI. Since the redirection might be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. This response is only cacheable if indicated by a Cache-Control or Expires header field.

Answer 2

按照http1.1的标准，302状态只能是Found，没有Moved Temporarily，所以Move Temporarily估计只是一个不标准的描述而已
虽然status code后面的描述是可以自定义，但是既然使用了http协议，还是应该按照他的标准来做

http status code以及描述可见w3c文档：http://www.w3.org/Protocols/rfc2616/r...

我来抛一个问题：
如用weblogic或者tomcat部署仅有一个应用如A，然后用curl命令发一个HTTP请求但是发送的时候修改了Host头
1 http://ip:port/A --> 返回302 Moved Temporarily
2 http://ip:port/A/ --> 返回正常，可能是A应用下的index.html
3 http://ip:port/B --> 返回404
自己对上面的现象比较疑惑，希望高手解答一下
