Reason being - I have an html/Ajax Air app that after update I have had issues with users getting odd behaviours with my app until they clear their browser cache. I know there is a difference between OS & Browser cache, eg it looks as tho both IE & Safari use OS caching where Firefox uses itself/the browser to store cache & cookies etc.
All comments welcome.
AIR has a property called useCache. This tells it to use the cache or not while using AIR's built-in embedded browser. http://livedocs.adobe.com/flex/3/langref/flash/html/HTMLLoader.html#useCache
AIR has no APIs that let you clear the OS's browser cache. But you do have FileSystem APIs so if the cache can be cleared by deleting particular files, you'd be able to do it.
But if it involves any other settings (like a registry, or a custom way of parsing an index file), then you might run into trouble doing it.
