Varnish Caching

If you are experiencing missing pages when using a Varnish caching server with SureFeedback you might try and use the following rules to help prevent this:

In your Varnish Configuration:

// Tells Varnish to pass through on the website script loader 
if (req.url ~ "ph_apikey") { return (pass); }  

// Tells Varnish to pass through on the access token urls 
if (req.url ~ "access_token") { return (pass); }
