I'm using nginx as a reverse proxy for multiple environments hosted on the same IIS server. I'd like to use the same caching settings for all environments except development, which nothing should be cached.

Is it possible to tell nginx to never cache anything if the url contains the pattern "project_dev" anywhere in the address?

Have a look how map is used in 'nginx-simple-WAF.conf' in the /conf folder from package in my sig.

Map is your friend here.
