           Summary: Web Inspector: uses a different User-Agent string than
                    the "inspected" window
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: joost.dekeijzer at gmail.com

When the inspector is enabled, it tries to fetch .map files for compressed javascript files.

When fetching, the User-Agent "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9) AppleWebKit/537.71 (KHTML, like Gecko)" is used, where the browser window itself uses "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9) AppleWebKit/537.71 (KHTML, like Gecko) Version/7.0 Safari/537.71"

In web applications with (very) strict security settings, a different User-Agent string can result in a logout. I've had this happening in a CakePHP application where User-Agent checking is a default security measure.
