They've done exactly this with https://example-com.translate.goog https://example-com.translate.goog

  Yeah. Though they have a potential bug with domains that end in a dot. For example, my website translated with their service: https://splet-4a-si.translate.goog/?_x_tr_sch=http&_x_tr_sl=sl&_x_tr_tl=en&_x_tr_hl=sl&_x_tr_pto=wapp https://splet-4a-si.translate.goog/?_x_tr_sch=http&_x_tr_sl=... Clicking on the link "version control" leads to the page https://ni-xn----ijanec--9jb-eu-.translate.goog/?_x_tr_sch=http&_x_tr_sl=sl&_x_tr_tl=en&_x_tr_hl=sl&_x_tr_pto=wapp https://ni-xn----ijanec--9jb-eu-.translate.goog/?_x_tr_sch=h... (note the second label ending with -) and this page can't be reached according to google, but on the real site (http://splet.4a.si http://splet.4a.si), the link is valid: https://ni.šijanec.eu./ https://ni.xn--ijanec-9jb.eu/ Another pretty bad aspect of their domain handling (replacing dot with -) is that they can't support really long domains that exceed the length of a label. Secondly, this breaks punycode parsers and instead of "šijanec" as a label you get some garbled unreadable punycode. Label length problem: Website http://splet.sijanec.sijanec.sijanec.sijanec.sijanec.sijanec.sijanec.eu http://splet.sijanec.sijanec.sijanec.sijanec.sijanec.sijanec... cannot be unambiguously page-translated with their service. -- they remove the first s in the hostname, yielding: https://plet-sijanec-sijanec-sijanec-sijanec-sijanec-sijanec-sijanec-eu.translate.goog/?_x_tr_sch=http&_x_tr_hp=s&_x_tr_sl=sl&_x_tr_tl=en&_x_tr_hl=sl&_x_tr_pto=wapp https://plet-sijanec-sijanec-sijanec-sijanec-sijanec-sijanec... EDIT: they seem to add a get parameter _x_tr_hp=s, so this is probably how they work around the limitation. Nice! They could've done www.website.example.translate.goog, but that would add issues with TLS, since a wildcard subject alternative name only matches one label. But by getting a CA signed cert, limited to translate.goog (which is possible), they could just issue certs on the fly.

    The amp version gets around the length by hashing the hostname if it's too long: https://amp.dev/documentation/guides-and-tutorials/learn/amp-caches-and-cors/amp-cache-urls https://amp.dev/documentation/guides-and-tutorials/learn/amp...

      Interesting, but that means they have to store the hostname somewhere.
      • gregable 3y ago
        It's repeated in the URL path, not just the hostname.

          Ah, I see!
