Symptoms

MS Internet Explorer 8 browser clients are seeing pop up windows during testing that show an HTTP 400 error code. The pop up errors happen with an ADF 12c application that has Apache 2.4.x web server in front of WebLogic Server.  The 400 errors occur most often when there is increased network latency.
