crossdomain.xml prevent caching

After changing domain name where flash application being hosted I should change crossdomain.xml file. That crossdomain.xml is hosted on api-server, which is used by flash application. I see that flash uses crossdomain.xml from browser's cache. Is there any trick to make flash to not get crossdomain.xml from cache? Maybe there is any parameter, that I can pass to flash during it's call in object tag?
