Sure, I'm familiar with tor2web, I'm even on the mailing list ;) But as far as
I can tell, this is because the .onion does not necessarily expect to get a
request for https://duskgytldkxiuqc6.tor2web.org/ and not
http://duskgytldkxiuqc6.onion/ - but as far as I understand translation mode,
it's meant for enabling hidden (web) services to be accessible from for example
a regular mobile browser, yes? With the config from above, it's trivial to get
the HS to respond to https://exampledomain.org/ (shouldn't be a problem serving
the correct SSL certificate from the HS itself, even though I haven't tested) -
the magic of adding headers and disclaimers wouldn't be done by tor2web but
you'd have to handle that on the hidden service itself ... Which is still easy
because you do actually get passed the Host: header enabling distinguishing
connections.

Right, see https://www.cryptoparty.at/tor2tcp#anonymity

The connection pooling is cool though, and the part that I have the least
understanding of.

I'm not advocating this as an alternative to tor2web or even anonymous access
to anything, but I guess it's just a more lightweight approach to the
"translation mode"? It only works with one hidden service per public IP anyway.

My interest mostly stems from trying to run a SMTP hidden service that also
works with SSL on clearnet, giving the "public face" VPS as few as possible
(i.e. no SSL key, no MTA that might even cache messages if the HS isn't
responsive) ... But that's enough veering off the original topic for now.

Best, Michael
