As mentioned in the discussion about link handlers and webpage content rewriting, I once looked into using Web proxy software to do the latter. One complication was that Dillo doesn't support a feature equivalent to setting the https_proxy environment variable for GNU Wget, whereby the proxy acts as the HTTPS endpoint for encrypted Web server connections and sends the data back to the browser unencrypted. This allows the proxy to manipulate page content without needing to transform HTTP requests into HTTPS requests and rewrite https:// in page URLs as http://. Besides proxies, for old computers where performance or available TLS library versions prevent using modern encryption, this also allows the encrypted communications to be offloaded to more modern computer. Or using a different encryption library that's optimised for old computers, as described here: http://oldvcr.blogspot.com/2020/11/fun-with-crypto-ancienne-tls-for.html For using this with old computers, it would be ideal if the HTTPS proxy feature was available even if Dillo is compiled without linking to a TLS library. Also the https_proxy environment variable should be set to the HTTPS proxy hostname when running Wget for downloads so that it applies to those as well.
