Multiple websites on one server

Hi, firstly I love your plugin! I use it on a few websites and it’s great!

I have a Ubuntu nginx server with redis on it, with 2 websites. I tried installing this plugin on both websites and running it, but I was experiencing weird redirect issues, where one domain redirected to the other. As soon as I cleared the redis cache and disabled redis, it was back to normal.

I’m assuming it had to do with both websites using the same database. But I’m not an expert.

What kind of setup would you recommend if I only have one redis instance with multiple websites? Multiple databases? And is it possible using this plugin?

Thanks!!
