           Summary: XMLHTTPRequest should invalidate cache unless method
                    is GET
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: natevw at yahoo.com


According to RFC 2616 13.10 ( http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13.10) , "some HTTP methods MUST cause a cache to invalidate an entity" including POST. However, issuing a POST to a URL via XMLHTTPRequest fails to cause WebKit to invalidate its cache for the requested URL. This prevents dynamic web pages from using a POST to invalidate resources (such as images) that are known by the client side scripts to have been updated.
