see the No.17197, it wail 30 second
sometime iOS Safari And WebView load page will wait 30s.
from HTTP waterfull, it seem Client hold the request at 30 second.
from TCP dump, it seem client TCP timeout, the 30 second request be sure happen after [FIN].
Now this url can not reappear becouse i disabled Nginx HTTP keep-alive for iOS. But i still received 30 seconds report.

i have check again, when i disabled keep-alive for ios, this bug is disappear。
This is most likely a known bug below WebKit tracked by Apple as rdar://problem/5616696. Disabling keep-alive is the correct workaround.
