Localhost, spelled wildly

Oct 15, 2026 · @Michal Čaplygin

Each spelling below parses as http://<spelling>/ to the address of its section, in Node 22 (a URL Standard parser) and Chrome 155; where only Chrome accepts a spelling, the row says so. Firefox 159b2 (Developer Edition) agrees with Node on every row. A real request to a local server also succeeded for every spelling Chrome accepts, with the shown host in the Host header.

Every spelling is a link to / of that host, so a click tests it in your own browser.

Name: localhost

Could you point out any grammatical errors or instances of awkward or unnatural phrasing I’ve made in this conversation? Please skip minor typos that result in non-existent words, but do let me know if I’ve used the wrong word entirely. Please format the feedback with the original and corrected versions on separate lines, and bold the differences.
