 * Hi there,
 * I have some dynamic content, let’s say for instance: an instagram widget that
   pulls the latest images from an account. So I want this widget to be updated 
   roughly every 4 hours, if the cache gets deleted before, it doesn’t matter as
   it’s not critical.
 * I was thinking of making a transient that would capture the contents from instagram
   an make a mfunc cache exception so w3tc serves the cached contents except the
   instagram widget that comes from its transient.
 * Am I completelly wrong or how would you go about this?
 * As an extra question, how do you configure properly ngin-x as a reverse proxy
   with w3tc given the above information?
