title: Wordpress w3 total cache and load balancing concerns
body: <p>The website we are working on right now will be hosted on two load-balanced IIS servers. The database will be common, on a third server.</p>
  
  <p>The plugin (w3 total cache) saves all the files on the disk, inside a wp-content/cache folder.
  Right now we are using only one server so everything works fine, but we have to attach the second one soon to the load balancer.</p>
  
  <p>My question is:
  - Is it safe to attach the second server as is, without any modification in the plugin ? Do we encounter a risk of the html inserting a cached css file for example, that is present only on one server and not the other ?
  - If it is not safe, would a shared wp-content/cache folder solve the issue (symbolic link or so) ?</p>
  
  <p>Regards</p>
