# needs to exist and be writable by nginx www-data:www-data

pagespeed FileCachePath /var/ngx_pagespeed_cache;

In every server block where pagespeed is enabled add:

#  Ensure requests for pagespeed optimized resources go to the pagespeed
#  handler and no extraneous headers get set.

location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" { add_header "" ""; }
 location ~ "^/ngx_pagespeed_static/" { }
 location ~ "^/ngx_pagespeed_beacon$" { }
