hi all,
this is driving me nuts.

My client code:
I call the server once for each node in the array endpoints.

but the result (see below) is three calls with the last element (/times) i have tried a zillion times in vain, they all ends with three (/times) call. the only way i can get this right is by break out the calling logic to a function like void spawnRequest(string ep){...} and thus creating a copy per call I suppose.

Two things:
It works but, it is a clumsy solution.
And I'm not really sure why it goes wrong.

i would appreciate if someone can show me a clean solution without a 'technical' function. and why my solution goes wrong

import vibe.vibe;
import std.stdio : writefln;
import std.stdio : writeln;

    void main(){

string[] endpoints = ["/", "/hello/VibeClient", "/time"];

        foreach (endpoint; endpoints) {
                writeln("start ",endpoint);
            auto ep = endpoint;
            runTask(() nothrow @safe {
                try {

auto response = requestHTTP("http://127.0.0.1:8080"; ~ ep); auto body = response.bodyReader.readAllUTF8();

                    () @trusted {
                        writefln("[%s] Response: %s", ep, body);
                    }();
                }
                catch (Exception e) {
                    try
                    {
                        () @trusted {

writefln("[%s] Error: %s", ep, e.msg);

                        }();
                    }
                    catch (Exception) {}
                }
            });
        }
        runApplication();
    }

result:
PS C:\Users\Lasse\DUB\nwclient01> ./nwclient01.exe
start /
start /hello/VibeClient
start /time
[/time] Response: Current time: 2026-02-02T17:28:07.6319941
[/time] Response: Current time: 2026-02-02T17:28:07.632999
[/time] Response: Current time: 2026-02-02T17:28:07.632999

Use:

```d
runTask(() nothrow @safe {...}, ep );
```
