Nginx with proxy_pass and local static cache won’t serve images from the proxy location

Morning gentlemen,

So, the problem I'm having right now is that I want this setup to work:

http://qwe1.com/

This request should go to Apache and get all images from the static content folders, this works very well with this config.

http://qwe1.com/forum 

This request should be proxied to server2 (proxy.qwe1.com), this also works very well now.

http://qwe1.com/forum/example.jpg 

This request should also be proxied to server2 since it has to do with the same forum, this does NOT work today due to the static cache directives. It matches the static cache directives and tries to find the image locally on disk and gives me a 404 in the static.error.log which you can see below. If I comment out the static cache directives I get the desired setup, but I'd really want to run that cache as well of course.

I tried sorting this out with the help of rewrites, I've tried these solutions so far

        location ~* ^(?P<part_uri>/forum/.*\.(css|js|jpg|jpeg|png|swf|gif|svg|ttf|eot))$ {
            proxy_pass      http://proxy.qwe1.com/forum_en$part_uri;
            proxy_redirect  off;
            proxy_set_header        Host $host;
            access_log /var/log/nginx/TMP.log;
            error_log /var/log/nginx/TMP.log;
    }

This solution basically forwards everything from http://qwe1.com/forum to http://qwe1.com/ somehow, I've not really managed to figure out why, at least it doesn't work.

I've also tried this solution

rewrite ^(/forum/*\.(css|js|jpg|jpeg|png|swf|gif|svg|ttf|eot))$ /forum_en/$1;

    location /forum_en  {
            proxy_pass      http://proxy.qwe1.com;
            proxy_redirect  off;
            proxy_set_header        Host $host;
            access_log /var/log/nginx/TMP.log;
            error_log /var/log/nginx/TMP.log;
    }

Which gives the same symptons as the earlier one, I get redirected from http://qwe1.com/forum to http://qwe1.com/

Any ideas folks?
I have the whole config here beneath.
Thanks in advance.

## one.qwe1.com = server1
## proxy.qwe1.com = server2

                proxy_redirect  off;
