NGINX as proxy before apache, and localy store php generated images

[Jaroslav]

Hello everyone,

I am using nginx as proxy before apache a long time already. And it is
really terrific what it does.
Ram usage dropped like 3 times
I mainly set up image cache headers in nginx config

Today I've spotted, that one of vhosts is generating images ALWAYS on the
fly, images are accessed like:
/bin/825?w=121&h=87&cutted=fit
/bin/4999?w=222
/bin/5113?w=121&h=87&cutted=fit

etc..

I wonder is there any way I can tell nginx to store those images locally,
ie for a week, and serve them
to other users, so it won't be resized multiple times?

I tried googling but don't even know how/where to start from..


Thank you in advance!
