=== TraceHandler

Jooby doesn't support `HTTP Trace` requests by default. To support them you have two options:

- Use the built-in `TraceHandler`
- Write your own trace handler

The javadoc:TraceHandler[] supports `TRACE` requests over existing handlers.

.Head Example
[source, java, role = "primary"]
----
import io.jooby.Jooby;
import io.jooby.TraceHandler;
...
{
  
  decorator(new TraceHandler()); <1>
  
  get("/", ctx -> {
    ...
  });
}
----

.Kotlin
[source, kotlin, role = "secondary"]
----
import io.jooby.Jooby
import io.jooby.TraceHandler
...
{
  decorator(TraceHandler())      <1>
  
  get("/") {
    ...
  }
}
----

<1> Install TraceHandler

`TRACE /` performs a message loop-back test along the path to the target resource, providing a
useful debugging mechanism.
