vga.zol.com.cn - desktop site instead of mobile site

[MDTsai]

URL: http://vga.zol.com.cn/ Browser / Version: Firefox Mobile 51.0 Operating System: Android 5.0.2 Problem type: Desktop site instead of mobile site

Steps to Reproduce 1) Navigate to: http://vga.zol.com.cn/

Chrome and UCMobile browser works fine. After change UA to chrome mobile, Firefox can receive mobile site.

The following URLs under zol.com.cn have the same problem: http://www.zol.com.cn/ http://detail.zol.com.cn/ http://xiazai.zol.com.cn/ http://mobile.zol.com.cn/ http://desk.zol.com.cn/ http://news.zol.com.cn/ http://nb.zol.com.cn/

These don't have such problem: http://bbs.zol.com.cn -> http://m.zol.com.cn/bbs/# http://ask.zol.com.cn -> http://wap.zol.com.cn/ask/

Eric said this is a super important site, top 50 in China -- candidate for UA override if we can't get traction with outreach after a week or two (to give them a chance to fix).

It seems like the redirect is on the client-side. Looking...

Interesting meta elements here, don't think I've seen that before.

<meta http-equiv="mobile-agent" content="format=xhtml; url=http://m.zol.com.cn/vga/?j=simple&via=index">
<meta http-equiv="mobile-agent" content="format=html5; url=http://m.zol.com.cn/vga/?via=index">

Anyways, the JS is here inline:

<script type="text/javascript"> 
if(/AppleWebKit.*Mobile/i.test(navigator.userAgent) || (/MIDP|SymbianOS|NOKIA|SAMSUNG|LG|NEC|TCL|Alcatel|BIRD|DBTEL|Dopod|PHILIPS|HAIER|LENOVO|MOT-|Nokia|SonyEricsson|SIE-|Amoi|ZTE/.test(navigator.userAgent))){
    if(window.location.href.indexOf("?via=")<0){
        try{
            if(/Android|Windows Phone|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)){
                window.location.href="http://m.zol.com.cn/vga/?via=index";
            }else if(/iPad/i.test(navigator.userAgent)){
            }else{
                window.location.href="http://m.zol.com.cn/vga/?j=simple&via=index"
            }
        }catch(e){}
    }
}
</script>

So, if you're a mobile Safari, OR you have one of a number of device IDs in the UA string, send to mobile.

@MDTsai can we try outreach here? If we don't have luck, a simple UA override would be to simply put in a UA token like LG or SAMSUNG for this site.

Still no response from zol.com. Move to gofaster addon?
