I enabled Varnish and works fine on html websites, I check it using this site
http://www.isvarnishworking.com/ . But if I try wordpress sites I get this response when test if Varnish works:
Yes!
Sort of!
Varnish appears to be responding at that url, but the Cache-Control header's "max-age" value is less than 1, which means that Varnish will never serve content from cache at this url.
The max-age value appears to be: 0
This may be intentional, but if you want Varnish to cache this url you'll have to fix the max-age value the application is sending to Varnish.
And here, for you to ponder further, are the actual headers we received:
The url we checked: zumzi.eu
HTTP/1.1 200 OK
Server: nginx/1.5.6

Can I use this tutorial safely
http://wiki.scalr.com/display/docs/Inst ... +WordPress ? Or should I let it as it is because the response in normal ?
