What is the easiest way to have some function called by the `HttpClient` on each outgoing request, which is able to modify the request (e.g. add a header)? It's just going to be used in tests, so it's not a problem if it's a bit of a hack

My intuition is that plugins allow to do that, but I'm not familiar with them

<https://ktor.io/docs/default-request.html>

There’s a header section of that plugin
<https://ktor.io/docs/default-request.html#headers>

you can also use a custom plugin <https://ktor.io/docs/custom-plugins.html#on-call>

<@U0282PZ5BSN> I know about default request, but the header is different every time, that's why I want the ability to run code on each request

Sorry, the link you sent is for server-side plugins
