Hi, @MingSheng92. Everything will be prerendered if the HTTP request header user-agent contains one of the strings that triggers our prerendering service.
The most common user-agent I use when testing is “Twitterbot”. There are curl examples in this post:
To summarize, I can request the prerendered version of a URL with curl using this:
curl -A Twitterbot <URL HERE>
If there are other questions about this, please let us know and we will be happy to answer.
