issues about nginx proxy_cache

[J.J J]

If you access it correctly, nginx will send the request to backend and pass
response which is 302-redirect-link in your case back to the browser.

Check the "302-redirect-link", I think it should be an address to
http://192.168.15.159:7090 not to nginx(port 8064/8065), that's why the
browser bypasses nginx.

Also note, proxy_store does nothing to the stored file, it's quite
different from proxy_cache.
