Not only does VasSonic supports the static or dynamic websites which are rendered by server, but it is also compatible with web offline resource perfectly. VasSonic uses custom url connection instead of original network connection to request the index html, so it can request resource in advance or parallel to avoid waiting for the view initialization. In this parallel case, VasSonic can read and render partial data by WebKit or Blink kernel without spending too much time waiting for the end of data stream.
