How does Gmail do comet on Opera?
- by Unknown
I would like to know how Gmail (or anyone else) does comet on Opera.
Here is what I know so far from my experiments.
It doesn't use the event-source tag which is broken in Opera 10.51.
It doesn't use iframe which displays a spinning throbber and a busy mouse cursor.
It doesn't use responseText on xmlhttprequest when readyState = 3 which is known to be broken on Opera.
I tried seeing how it was done in mibbit and etherpad, and I found that they both use long-polling.
