As mentioned, does Baidu support Google's specifications for crawling ajax requests?
For example, accessing a page of a single-page application
http://xxx.com/xxx/xxxxx
Baidu can detect
<head>
...
<meta name="fragment" content="!"></head>
Does this metadata redirect access?
http://xxx.com/xxx/xxxxx??escapedfragment_=
