我有多个网址需要使用Nginx添加相同的标头集.这是文件名.

File Group1
    https://www.example.com/news/2017-08-03/article-xyz/
    https://www.example.com/news/2017-08-03/article-xyz/topics/
    https://www.example.com/news/2017-08-03/article-xyz/gallery/
File Group2
    https://www.example.com/news/2017-08-02/article-abc/
    https://www.example.com/news/2017-08-02/article-abc/topics/
    https://www.example.com/news/2017-08-02/article-abc/gallery/

所以在这种情况下,文件组1需要：

add_header Cache-Tag  article-xyz;

而文件组2需要：

add_header Cache-Tag  article-abc;

所以Nginx.conf应该是这样的

  location /news/ {
        add_header Cache-Tag  article-abc;
    }

但是如何在添加标头中动态应用它？
