Building and updating map caches with arcgis server 10

With this option, the tool re-creates only the tiles that cover the features of a feature class that you supply. For example, if you have a cache covering the entire United States and you just edited the national park boundaries, you can choose "Update specific areas using a feature class" and supply the national parks feature class.Only tiles in the national parks will be re-created.

When displaying cached map services, Arc GIS clients store tiles locally so that they don't have to be retrieved again when the user navigates back to the area.

Even when you've updated your cache, people who have used your cache before may have some of the tiles stored locally on their machines.

When you create a map cache, you are creating a snapshot, or picture of your map at the time you create the cache.

When you edit or update the data, two things need to happen before others can see the changes: Updating the cache involves re-creating some or all of the tiles in your cache.

You can update the cache using the Manage Map Server Cache Tiles tool.A simple way to access this tool is to open the Service Properties on the Caching tab and click Update Tiles.Once the tool opens, find the Update Mode and choose Recreate All Tiles.On Linux/Solaris, you can create/update cache from command line.If you want to only update tiles in a certain rectangular area of the map, you can change the default Update Extent, which is the extent of the entire service.If you know that features in only one dataset or one geographic area have changed, you can check the option to "Update specific areas using a feature class".
