在重定向的外部URL上设置标头 [英] Setting headers on redirected external URL

问题描述

jsf应用程序是否可以导航到外部链接并指定该外部链接的标头？
到目前为止，我试图调用支持bean方法：

Is it possible that a jsf application can navigate to an external link and specify headers for that external link? So far I have tried to call in the backing bean method:

ExternalContext#setResponseHeader(java.lang.String name, java.lang.String value)
ExternalContext#redirect(java.lang.String url) 

重复次数成功执行但标题丢失。
有没有办法指定带有标题的链接？

The redicection is successfully executed but the Headers are lost. Is there any way to specify a link accompanied with the headers?

推荐答案

不，HTTP不允许在不同的请求上设置标头。

No, HTTP doesn't allow setting headers on a different request.

标题必须由目标URL后面的代码设置。 您错误地认为以这种方式解决的任何问题肯定会以不同方式解决。

The headers have to be set by the code behind the target URL. Whatever problem you incorrectly thought to solve this way has definitely to be solved differently.
