Well I almost had something working. I added /1234567890 on to the
end of a URL and set up a simple redirect like s@/1234567890$@@. It
worked OK for http, but of course not for https.

Then I tried adding a subdomain 'forward-socks5.' to the start, but
it fails with this error:

Error: pcrs command "s at forward-socks5.@@" changed
"forward-socks5.duckduckgo.com:443" to "duckduckgo.com:443" (1 hit), but the
result doesn't look like a valid URL and will be ignored.

Why is this URL seen as an error?

The actual URL I entered in the browser was

https://forward-socks5.duckduckgo.com/lite/

Thanks for any help.
