Process xml speed (JS vs AS) for hybrid site (utilize cache)

programming flash
1

I’m planning on building a hybrid site that will be published using flash 8 for the nav and will be updatable with xml.

  1. Does xml stay cached within the same swf between pages? If so, would it be better to make the flash nav “see” the full xml file regardless of the section the user is in. (alternative would be to break up the xml file server side and feed the flash only what it needs at the time).

  2. Would it somehow be better if JavaScript broke up the xml and then fed it to flash?

  3. I know remoting would be the best way, but that isn’t an option for this project. Are there any other avenues that you would suggest for a hybrid site?
