Summary:

Ajax只是利用脚本访问对应url获取数据而已,不能做除了获取返回数据以外的其它动作了。所以浏览器端是不会发起重定向的。

个人理解正常http url请求和ajax请求的区别:
Copy after login
1)正常的http url请求,只有浏览器和服务器两个参与者。浏览器端发起一个http请求,服务器端处理后发起一个重定向,浏览器端从response中获取到重定向地址,发起另一个http url请求。也就是说,浏览器会按照response中的内容进行响应(如重定向),这是浏览器的功能决定的就得响应。

2)Ajax请求,参与者就有三个即ajax、客户端、服务器,ajax处于客户端和服务器两者之间。过程是客户端发起一个ajax请求,服务器端处理后,如果发起一个重定向,然后ajax会怎么办呢?它只会获取刚才请求返回的数据,其他的任何动作一概不去做,ajax是这么做的(ajax功能就是这么设定的,ajax框架源代码也是这么写的)。

也就是说,引入了ajax之后,ajax就插在浏览器和服务器之间了,服务器给浏览器的response被ajax拦截了,但是ajax本身却什么都不做,也不转达。

In other words, if you want to implement redirection, you have to code it yourself. , that is, transform ajax. Reference: http://blog.csdn.net/ideality_hunter/article/details/61620875
