JavaScript XmlHttpRequest 在 Android 上保持活动状态

Question

I am trying to build a website (intended to be put into a PhoneGap app) that displays messages it is sent via HTTP push (long polling, comet, ..). For this I need a connection that is kept alive by the client. However, the Android browser seems to always close the connection immediately and does not allow me to set the Connection: keep-alive HTTP header.

Is there a possibility to connect to the server and keep the connection alive?

Thanks in advance:) MT

what you need is to use an implementation of some kind of HTML5 Websocket. So far as I know, there's no direct implementation of that WebKit feature in Gingerbread 2.3.x yet, nor Phonegap but there's a workaround by library in Phonegap:
