Define filters
Be careful, this step should not be done if you have perfectly followed the previous steps.
Only in the case where you have defined a route predicate different from /**.
We have defined the route predicate as /**.
In our case, it is not necessary to define a request filter. You can skip this step.
Path prefix
However, if we had defined a route path different from /**, it would be necessary to define a request filter.
Imagine that we had defined the route path /httpbin/**.
This means that if I did:
curl http://localhost:8080/httpbin/get
I would expect it to respond in the same way as if I did:
curl http://httpbin.org/get
But in the current state, this is what would be executed.
curl http://httpbin.org/httpbin/get
This is not what we want.
Strip prefix
To fix this, we would need to add a request filter that will remove the prefix that allowed us to condition the route.
To do this, we would use the stripPrefix filter with a value of 1 (removal of one element).
