Not a book, and I only have one (positive) data point from a coworker, but this free Udacity course tackles that subject:
Udacity has a Networking for Web Developers course[0], but I'd recommend trying out things (such as running a simple web-app on your own server). Things like:

- Running

- Trying out a few different web servers (apache/nginx/caddy)

- Playing around with load-balancers on $cloud_provider.

- Spending time with docker networking (

- Playing around with various X-Forwarded header options in the context of your application

For a web developer, the most useful skill is knowing what each and every component on the pipeline is doing before your code executes on the request. As a common eg, if your application seems to be loading stylesheets from `http://` instead of `https://` despite being loaded over HTTPS, it is often because your application didn't honor the X-Forwarded-Proto header (which most frameworks will do for you). Similarly, seeing a local IP address (192.168.x.y for eg) on a log, and realizing that you should be using the X-Forwarded-Ip by "trusting your proxy"[1] and doing it securely[2].[3].
