How can I learn more about server-side technologies?

Get yourself a VPS, set it up from scratch and run some non-critical websites on it (nothing with private user data since you can’t be sure you’ll set it up securely). Both Slicehost and Linode offer a good set of guides to a whole host of common tasks:

I would like to setup a web-server which will be used solely by myself. What would be the safest way to do so in terms of confidentiality of the contents?

I haven’t configured them myself, but it might be worth looking in to client SSL certificates for this. That way your server won’t communicate with any browser that hasn’t installed a certificate which you generate. I believe the BBC used to use this for a lot of their important servers which they wanted to be accessible only by their own developers from across the internet (I don’t know if they still do).

How can I determine which web server a particular website is using (Apache, IIS, Nginx, etc)?

If you’re on Linux or OS X, use curl with the -I option (to make a HEAD request and see the HTTP headers):

What are the advantages of running Apache behind nginx as opposed to just Apache by itself?

I do this for all of my Django stuff—I have Django running on modwsgi on a stripped down Apache (almost no configuration except for the modwsgi stuff), then I put an nginx on port 80 which serves the static files directly and proxies dynamic requests back to Apache.

What is the largest production deployment of Server Side JavaScript?

I believe Flickr used to use Rhino for scripting the image processing (resizing, thumbnailing, sharpening) that was applied to every single uploaded photo. No idea if that’s still the case though.

FAPWS3-0.2 (WSGI server based on libev). Another strong contender for Python’s answer to Mongrel—3500 requests/s for static files, 43 for a simple dynamic (Django powered) pages and 4.8 for a heavy SQL query—all benchmarked with 300 concurrent requests. # 25th February 2009, 10:21 pm
