Despite the advantages of centralized hosting of SWZ files, in that it speeds initial load times for Flex applications after the first load, I have an issue with centralized SWZ files under the Adobe model, in that it exposes an inherent security weakness: if the centralized cerver hosting the Flex SWZ files ever crashes, every Flex SWF in the entire internet using SWZ caching ceases to function. You can build redundancy failovers, but that is still vulnerable to DoS attacks.
Which is why, despite the sacrifice in efficiency, the decentralized Apache SWZ model makes a lot more sense: individual companies host their own SWZ files for their own applications, so that if a DoS or similar attack prevents a Flex app from accessing the SWZ, only that company's Flex apps are affected, not the entire internet's-worth of Flex apps which use SWZ loading. _______________________________________________________________________ Joseph Balderson, Flex & Flash Platform Developer :: http://joeflash.ca Author, Professional Flex 3 :: http://tinyurl.com/proflex3book Sean Thayne wrote: > Hey Justin, > > Am I wrong that Apache versions of Flex do not have SWZs, they only have > RSL SWFs, correct? > > Back with Adobe Flex, SWZs allowed the app to take a while to load on the > first run, but afterwards they cached, so the next open would run very > quick.
