Google PageSpeed module: how to stop it to change the Cache-Control header on NGINX

I'm trying to stop Google's PageSpeed module to modify the Cache-Control header using nginx.

Within Apache I'm able to stop it with these two instructions:

ModPagespeedModifyCachingHeaders off
ModPagespeedDisableFilters extend_cache

Is there an equivalent of ModPagespeedModifyCachingHeaders on nginx?

I tried with:

pagespeed DisableFilters extend_cache;

and also

pagespeed RewriteLevel PassThrough;

In both cases it adds the header Cache-Control: "max-age:300".

Solution

For nginx you would need to add this to the config to force PageSpeed to leave the original caching headers:

pagespeed ModifyCachingHeaders off;
