    Project mention: Ktor login session not working as expected | reddit.com/r/ktor | 2021-04-11

    Right, actually I gave you some unhelpful guidance... I just re-checked and actually the correct way to obtain auntetication via session IDs is the Authorization feature. The Ktor docs don't mention this method for some reason, but it should be easy enough to read the sources... There is also https://gitlab.com/nanodeath/ktor-session-auth-example for example. Sorry for my mix-up

    Project mention: Easier non-blocking approach for a from-scratch server? | reddit.com/r/Kotlin | 2021-01-06

    Ktor is a project that's not primarily focused on application performance but developer performance. It seems to be sth different than what you want to achieve. I don't think a lot frameworks... or any other framework writes its own low level io stuff from scratch, they mostly use https://netty.io/ because there's not too much room for improvement and it's complete, battle tested and so on. I lately came across https://github.com/hexagonkt/hexagon which seems to have a very solid code base based on modules modules modules, is kotlin first and they have an adapter for netty. The usage of the naked http server seems to be as easy as it can be https://hexagonkt.com/port_http_server/port_http_server/ and they are even listed on techempower benchmarks https://github.com/hexagonkt/hexagon/ .
