So I have hosting for example.com which runs Drupal. I am also using this hosting for serving other websites on the same Drupal installation, so obviously I have a multisite setup with eg bananas.com.
But when I point bananas.com to the nameservers for example.com it goes to example.com and not my Drupal site for bananas.com *except when I do a hard refresh (Ctrl+F5) at which point it does go to my Drupal site for bananas.com*
This confuses me - either it is resolving to the correct multisite or it isn't. Why would this change upon a hard refresh - and this isn't just a cache issue because it is happening everywhere and seems to "reset" every day.
I'm having problems trying to identify the issue, so does anyone have any suggestions?
