Dynamic Map requests same image consecutively

Hey all,

I have been tracking an issue at initial application load. When I add my dynamic map layer, it is making the exact same image call to the server twice consecutively. This only happens on the initial load of the map, when the layer is added. After that, the map calls are made as expected, which would be one image call per pan or zoom. Has anyone experienced this? Does anyone know what could trigger another map image request, not including a pan and zoom action. I have attached a screenshot of the request happening real time in fiddler. I will past the full urls of the requests below as well. I would appreciate any assistance in tracking down what exactly is happening.

Thanks

Eddie
