问题
I would like to use parallel AJAX HTTP requests with iPhone Mobile Safari (OS4). What is the max number of parallel connections?
回答1:
If I'm not mistaken, Safari uses at most 4 connections to the same server, but you can test it yourself using this little test case (if you have access to an iPhone, of course).
回答2:
Test site provided by Marcel returned 6 connections on my iPhone 3GS.
