Escape Fragment works, but user agent doesn't? about prerender

Hi @felixchan ,

This is expected behavior. Googlebot supports the _escaped_fragment_ protocol for websites rendered with Javascript, so we use that instead when supported. We only fall back to user agent for crawlers that do not support the protocol.

So if you're accessing your website, try another user agent or try the _escaped_fragment_ like this:

If you have an html 5 pushstate url:

http://www.example.com/user/123 == http://www.example.com/user/123/?_escaped_fragment_=

If you have a #! url:

http://www.example.com/#!/user/123 = http://www.example.com/?_escaped_fragment_=/user/123

Thanks. What user agent can I use to test that function?

Oh, sorry. The Prerender server doesn't do any user agent checking, that's the job of the middleware. The Prerender server only takes a URL and prerenders it (with _escaped_fragment_ turned back into #!). The Node/Rails middleware is what checks the user agent.
