Since the upgrade to iOS 6, we are seeing Safari\'s web view take the liberty of caching $.ajax calls. This is in the context of a PhoneGap application so it is
$.ajax
My workaround in ASP.NET (pagemethods, webservice, etc.)
protected void Application_BeginRequest(object sender, EventArgs e) { Response.Cache.SetCacheability(HttpCacheability.NoCache); }
