Hi guys,

I know that nginx proxy\_cache is based on url (page). The cache file is  
something like this :  
./c/a00b4dce27af1b06075339f598a4050c  
and it includes all the content of that page : text, image, banner, …

Suppose that I have a site map (on real server) like this :  
/page1.html  
/page2.html  
/page3.html  
/banner.jpeg

all the three pages are include the banner.jpeg by tag \<img …

The problem is, when I update the banner.jpeg with a new one (same file  
name) on the real server, and I’ve updated the cached file banner.jpeg  
on cached server (remove that cache file), but when I surf the  
page1.html on cache server, it’s still include the old banner.jpeg ☹

Is there any way to fix this ? without delete all related cached files  
?

I mean recursive update proxy\_cache.

Thank you very much.

Do you mean, browser still include the old banner.jpeg? So, that’s  
browser cache,  
not nginx.
