Does it work on nginx without the headers-more-module installed?

unfortunately i cannot add the module headers-more for nginx myself.
but the following directive throws errors and wont let me save it:

location ~* \.php$ { more_clear_headers ‘Pragma’; more_clear_headers ‘Expires’; more_clear_headers ‘Cache-Control’; add_header Cache-Control $wp_cf_super_cache_active; }

is the module and directive really necessary to operate? any workaround?

thanks!
