How to disable WWW caching in iOS?

Does anyone know if there’s a trick to force refresh WWW caching on iphone.

I know this trick:

WWW("http://myfile.xml?nocache="+randomnumber);

Unfortunately the app is already in the app store!!

Is there any server side setting (e.g., .htaccess) or some other way to force unity to reload the file instead of returning the cached file? It doesn’t happen in the editor, only on the iphone…

Is the iOS WWW caching behavior documented somewhere?

I think this might be a step in the direction you’re wanting.

It’s worked for disabling cookies for me. I actually need and use cookies, but Unity provides no way to delete them in UnityWebRequest after they’re automatically created in iOS so I am handling them manually.
