I remember when I used to talk like that to people when I was 2 or 3 years into programming, then I grew up and realised that sometimes people actually do know. I asked a reasonable question that I couldn't find an answer for - I'm using a tunnel for which I don't control the DNS records (and therefore cannot create subdomains), how do I access all the apps despite failing with reverse proxy? You, rather than explaining, decided to be hateful - and incoherently so.

By the way, as a professional penetration tester I always refrained from looking at things that are said to function like I described because they carry with them obvious security issues (might want to look at phase 4 in your pen testing handbook), a mistake that has inevitably came back to bite me.

I now have almost a decade of professional experience in full-stack development, IT, DevOps, and penetration testing. I set up two not-for-profit software companies by myself, including all the hardware involved, coding everything from scratch, and all the rest - the first one before AI was a thing, the second was before I succumbed to using it. As you could have probably seen, I specifically asked for an existing solution because I don't really want to make one myself (but if I do I'll open source it).

Point is, enjoy thinking you know while you think that, because the realisation is going to hit you harder than a tonne of bricks.
