In what cases would this occur? For example, while building a map cache? If a map cache was aborted? If you only built caches are certain areas of interest and the viewer panned outside an AOI? Thanks.

Does the custom 404 tile affect the behavior of future update operations on the cache? For instance, suppose I receive new data that contains features in an area where there didn't used to be any (so the "no data" tile had been displayed there). If I do an update and select "recreate empty tiles only", will the nonexistent tiles still be built properly? The update isn't confused in any way by these error tiles, is it?

The "data not available" tile should not affect the update. This tile is only returned when the client can't find any tile. If you add some new map tiles by updating the cache, then the server will return those new tiles instead of the 404 error.

Is this possible with the Java ADF (Tomcat)?

Under Tomcat, you have to edit the "web.xml" file of your webapplication like this:

This seems very simple but I'm not getting it to work. I think it may have to do with the way I am caching and updating the cache: I'm caching an area along the US/Mexican border where only the area along the border needs to ba cached at the largest scales, and the areas seen at the full extent, e.g. Indiana, are only cached at the three samllest scales. So far, I ahve the three smallest scales cached and one area of the border cached at all scales, however when I zoom in to one of the areas not cached at a larger scale, instead of getting the 'data not available' tile the map tries to render dynamically. (??) This also happens if I try to pan outside the area that I have cached. Any suggestions? Thanks

Hmm... if you're using ArcMap as a client, it is expected behavior that ArcMap draw the map dynamically if it can't get the tile. However, ArcMap should get the "Data not available" tile before it tries to do a dynamic draw. So I am not sure why you are not seeing it.

Another way to quickly see "blank" area without the overhead of a dynamic draw is to remove all layers from your map except one nonvisible layer that defines the extent. This could be thought of as "disconnecting" the cache from the map document. If you want to frequently update the cache or query layers in the cache, this method is not recommended.

This appears to have changed at 9.3 / 9.3.1 Have I missed something?

I have followed all the steps given to configure the "tile not available" image for 404 error. I am using AGS 9.3.1 on IIS 6.0. I am still not able to see the "tile not available image". I am seeing the map is blank and fiddler shows 404, when i zoominto the area. Is anything changed at 9.3.1? My mapservice is static, totally depending upon Tiles. I have a cache on E drive. Would that make any difference? I made the arcgiscache a "virtual directory" also. But still no luck. If anyone know the workaround through ASPX page also, i am ready to implement that? Thanks, Shail ...

I am also having trouble getting this to load with AGS 9.3.1. Is there a simple work around that is possible to show this 'data not available' image for uncached areas?

so, that's a "no," right? i am having similar problems.

Any change on how to do this for 9.3.1???

Yet another person having trouble implementing this on 9.3.1. What changed?

I got this to work, but I had to use the virtual directory URL - it would not work if I just used a file. However, the one that should support transparency does not - I'm going ot replace it with a blank .png.
