www.adobe.com/devnet/flashplayer/articles/fplayer9_security_04.html (the whole article is a must-read, but, this is the critical page) Flash Player 9,0,115,0 introduces new security measures that cause a flash SWF running in it to "make contact" via PORT 843 during xmlsocket connections! This is only the 1st step of what's to come: newer versions will REQUIRE policy files to be served up DIFFERENTLY (than they were required to, up until this version) and will cause headaches for us who host/run any socket server for use with Flash Clients. This change particularly caused issues with us, as, port 843 (a previously unused/unknown port) has always been in the realm of ports deemed to be in violation of firewall rules -- and in our case, by design and "in purpose" -- forced all clients who attempted such connectivity to have their IP blocked for a period of time, automatically -- REMEMBER -- this is ONLY for those clients who have this NEWER version of Flash9 installed and in use AND IF they call up an swf that tries to make an xmlsocket connection! So, take note, take heed, this issue is real and coming to all our doorsteps -- whether we like it or not. If you're not a developer or host, this affects you in such a way that: At some point, if not now, you'll not be able to use a site you've been using without issues alllll along.... until.... you updated your flash player -- UNLESS -- we developers/hosts read-up on the deal and follow the sheep!
