Rails spinoffs - Aug 2007 - Re: using Ajax.PeriodicalUpdater in iPhone

it''s probably the iPhone.

I mean, would you *really* want your phone to be connected to the internet
all the time?

Sure, it is a web application.

By the way, I have found something about this issue.

I saw a meesgae of "An JavaScript script is limited to running for
five seconds on the iPhone" on
http://www.tomw.net.au/technology/it/iphone.shtml.
So I guess maybe it was caused by net speed, after 5s, iPhone will
kill this request and lost related response which is need to active
next event by updateOnComplete().

But there are still a question, will iPhone limit a asynchronous js
code with 5s?
