Nginx-ssl ew prewarm

Hi,

I see lot’s of request from a user-agent “nginx-ssl ew prewarm”. Are there any information about what is this doing exactly ? The requests are landing on my non-www domain only, which is 301 redirected to the www. Another issue is that the requests are coming over HTTP1.1 Can it be the reason of ssl performance issues ?

Are you using Cloudflare Workers?

No, I don’t.

This is: Eliminating cold starts with Cloudflare Workers

You may not use Workers but we use them a lot internally. I wouldn’t worry about it though :slight_smile:
