            Bug ID: 140683
           Summary: Provide a way to bypass cache on page load
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: iOS
                OS: All
            Status: NEW
          Severity: Enhancement
          Priority: P2
         Component: WebKit2
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: stuartmorgan at chromium.org

In order to implement a "request desktop page" feature in an app using WKWebView, there needs to be a way to bypass the cache when requesting a load (so that the request with the desktop UA will get new, desktop resources, rather than using cached resources which may well have been tailored to mobile). This bypass should apply to both the main page, and to any subresource loads.

Chromium did this internally with UIWebView by using its own network stack, but since that's not possible in WKWebView a specific solution for this case is necessary.

This feature is important to users since there are still many sites that serve limited experiences to mobile users without any kind of escape hatch, so there are tasks that are simply impossible to perform on the web using a mobile device without this feature.
