Three questions

Hello,

Here are three questions, and really expect your professional support:

1. Does it support Multisite please?
2. We are running sever with nginx with Redis cache but not Apache, any suggestions upon configuration setting?
3. I am trying to use cache-busting function to solve tough problem: we want make the site running for both Pc browser and an App with the name of Wechat, but once we access a page in Wechat, it will show “please access”in Wechat on PC browsers since cache machanisim of Wechat. Hopefully we want to resolve the problem by using cache-busting, is this a right way please?

Thanks in advance!
