Question

I have pictures, and I want to add their headers to max, I have profile pictures which can be changed and post pictures, I want to add headers only for post pictures, but not to profile pictures, I have no idea how can I manage this. thank you, this is my configuration,

this is the path of posts, /post/name-of-the-picture.jpg  this is the path of users, /user/name-of-the-picture.jpg 

I only want to add headers to post path

location ~* \.(css|js|png|gif)$ {    expires max;    add_header Pragma public;    add_header Cache-Control "public"; }

Currently we have two options to solve this:

Option 1:

Duplicated locations: NGINX looks for the best match. (a little better performance)

location /post/ {     post config stuff;     .     .     . }     location ~* ^/post/.*\.(css|js|png|gif)$ {     post/files.(css|js|png|gif) config stuff;     expires max;     add_header Pragma public;     add_header Cache-Control "public"; } location /user/ {     user folder config stuff;     .     .     . }     location ~* ^/user/.*\.(css|js|png|gif)$ {     user/files.(css|js|png|gif) config stuff;     .     .     . } 

Option 2:

Nested locations: Filtered by extension in the inner location blocks

location /post/{     ...      location ~* \.(css|js|png|gif)$ {         expires max;         add_header Pragma public;         add_header Cache-Control "public";     } } location /user/{     ...      location ~* \.(css|js|png|gif)$ {         ...      } }
