pagespeed_static js_defer issues

[Antonio Laguna]

Hi here,

I've been watching some other topics about this subject but I can't see solutions applying to me. I've just activated the pagespeed module and I'm getting a non-cached version of pagespeed_static/js_defer. 

I've attached a screenshot showing the wrong ETag

This is the current configuration:

# sets the proxy cache path location, max size 2g

proxy_cache_path  /etc/nginx/cache  levels=1:2 keys_zone=STATIC:100m inactive=24h max_size=2g;

proxy_set_header        Host $host;

  }

}

upstream ghost {

  server localhost:2368;

  keepalive 64;

}

Any ideas?

I think you're missing some of the location directives from
https://developers.google.com/speed/pagespeed/module/configuration#module
:

# 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 ~ "^/pagespeed_static/" { }
location ~ "^/ngx_pagespeed_beacon$" { }

Seems I missed that!

I've added it and for now it had no effect. Added it on top of the first location if that matters. I

[Jeff Kaufman]

Could you paste your updated config?

Sure!

  # Needs to exist and be writable by nginx.  Use tmpfs for best performance.

  pagespeed FileCachePath /var/ngx_pagespeed_cache;

  # 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 ~ "^/pagespeed_static/" { }

  location ~ "^/ngx_pagespeed_beacon$" { }

Looking more at your config I see you have:

# default expires (browser cache) set to 1 minute
expires 1m;

Which explains the change I see, where js_defer now has see
"Cache-Control: max-age=60" instead of "Cache-Control: max-age=600".

(The 600s limit isn't applying anymore because its in "location /
{...}" and nginx only applies the most specific location block.)

Does it work for you to change:

location ~ "^/pagespeed_static/" { }

to:

location ~ "^/pagespeed_static/" { add header "" ""; }

?

If not, what about:

location ~ "^/pagespeed_static/" { expires off; }

?

Hi Jeff, 

Thanks for your help. It seems that last idea did the trick: expires off sends the correct caching headers!

Thanks a million and good eye!
