If the backend HTTP server replies with a 'Refresh' header to a request for an image or other non-text object, APM does not send this reply to the client.


If a web application uses automatic refreshing of some non-text objects (images or any other binary objects), the refresh might not work correctly.


This occurs with a response containing binary content that encounters an HTTP Refresh header.


There is no workaround.

Fix Information

Response headers are parsed correctly for any responses with unsupported content.
