[431] how to use the <keep-alive> in nuxt.js ?

hi, i has two page,

one is timeline, other is feed-detail

i hope the effect

1. enter website (default timeline page), load data (feeds) from api-server at hook mounted.

2. scroll some feeds... click one feed and enter feed-detail page.

3. click back up button of browser and return timeline page. now timeline reload the feeds and remount the page... scroll on top.

i hope the timeline page is not remount on back up.

i try such as:

<keep-alive>
    <nuxt>
</keep-alive>

but it is no effect, i'm inquisitive what the different between <nuxt> and <router-view> of vue-router ?

should me to do ?
