Backing up online documentation, part 2

Part 1

So now that we have some documentation backed up, how do we conveniently view it? We can write a serve.py script that looks like this:

#!/usr/bin/env python3
import http.server, ssl


class Handler(http.server.SimpleHTTPRequestHandler):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, directory="documentation/", **kwargs)


ssl_settings = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)
ssl_settings.load_cert_chain("cert/server.crt", "cert/server.key")

server_address = ("localhost", 8443)
httpd = http.server.HTTPServer(server_address, Handler)
httpd.socket = ssl_settings.wrap_socket(httpd.socket, server_side=True)
print("Serving on https://localhost:8443")
httpd.serve_forever()

Then generate server.crt and server.key with mkcert. However, what I'm interested in is automatically redirecting to the offline version if I visit the site in my browser. Fortunately, there is a very simple solution for this using the Redirector addon.

All we do is setup a rule that looks like this:

Redirect: https://example.com(/.*)?$
to: https://localhost:8443/example.com$1
Example: https://example.com/somepath → https://localhost:8443/example.com/somepath
Applies to: Main window (address bar)

Since our wget command will convert the links for local viewing, this should work transparently.
