ArcGIS Server 9.3, REST and Cache

After publishing a service if you make changes to the .MXD you need to clear the REST cache. There are a few ways to clear the REST cache:

1. Restart IIS – Super Easy
2. From the ArcGIS 9.3 REST admin page
   • The Admin page is located at: http://xxxxxxxxxx/ArcGIS/rest/admin/

Until you restart IIS the updates to the MXD will not be reflected in the REST service endpoint.
