Forcing Map Service Update

We are creating price contours at 5 minute intervals. I need the flex viewer to update and show the latest inverval every time the service is re-published (having to republish because of a bug with raster catalogs through rest endpoint). I have tried the autorefresh tag, but if the service is publishing when the viewer refreshes, there is no data shown until the next auto refresh interval.

Is there any way to push a refresh to the viewer. Meaning, the refresh would initiate when the service is republished in my services directory.

Any help would be appreciated.

Thanks,

Justin
