How I can purge the cache of mapviewer from an html page? The only way is cleare tile from mapviewer - manage tile? I've already set the mapviewer, mapbuilder and tilelayer with no cache but it doesn't work. If i change the value on the database, map viewer don't read the new value until I clear tile layer.
I too have struggle with rapidly updating tiles after making changes to the underlying data. I typically make use of the utility in mapBuilder to clear the tiles when necessary. I find this to be the most useful. You also need to make sure that it is not the browser cache causing the problem. Also, consider using vector data when possible, as it is more able to handle dynamic data.
