My question is, when yo开发者_Python百科u are in a webView, and you have gone through several pages.
You want to go back. Is the last page you have been to cached, so that you would not need internet connection to go back?
AFAIK, by default, WebView
works like a regular Web browser. While it caches things, it still makes requests (with If-Modified-Since
and related HTTP headers) to ensure that it has the latest editions. Also, WebView
presumably honors other cache control directives sent by the server, perhaps to not cache certain things.
You can use getSettings().setCacheMode()
on a WebView
to modify this behavior somewhat.
