Re: [Htmlunit-user] not work for a page in weather.com

[Xue-Feng Y. <xy...@no...>]

I have more progress now. After testing, BrowserVersion Chrome and
FireFox52(or the best supported) can reduce the job count to 2 in 5
minutes, and the data I needed is in webClient now. The others (FireFox45,
Edge, IE) can't reduce the job count to 2 in 5 minutes and I can't see the
data in webClient when the job count only reduces to 3 or more.

It's worth to point out that all real browsers I tested can show the data
in less than one minute.

Any more suggestion?
