Maybe this one:

import std.regex;
import std.array : appender;

static reg = ctRegex!"^/greeting/([a-z]+)$";

Oh, sorry, I forgot the reusePort option, so that multiple sockets can listen on the same port: 

    auto settings = new HTTPServerSettings("0.0.0.0:3000");
    settings.options |= HTTPServerOption.reusePort;
    listenHTTP(settings, &handleRequest);
Hi, would it be possible to re-share the example of vibe.d woth multithreaded support.
The pastebin link has expired and the pull request doesnt have the latest version. 

Thanks

Ade
I tried to run the example, and I'm struck with a linker error DMD v2.076.1 and LDC 1.4.0.
