My front-end is hitting /blog/content/foo/bar.jpg when looking for static assets.
How can I make NGINX redirect those requests to /content/foo/bar.jpg instead?

At first I tried this:

location ~ ^/blog/content/ {
    root /var/www/ghost/content/;
}

Apparently it didn't work – (btw, I'm testing each change in the .conf file with a sudo nginx -s reload + F5 in the browser.. is there a better way to test/debug NGINX behavior (and actually understand what's going on instead of this "worked / didn't work" feedback I get with each F5?)

Then, I tried this one I found in a cheatsheet – at the server level:

rewrite ^/blog/content/(.*)$ /$1 last;

Again, without luck. What bothers me is that I can't even see what the line above is doing and why it isn't working.

Someone, please, get me out of this "google for a solution -> try something that looks promising --> hit F5 hoping it works (it doesn't) -> google for a solution" loop.
