Let me just explain the differences between them. The radixtree_uri
router matches API requests with the existing route tree by URI path,
While the radixtree_host_uri matches the HTTP host and then matches
the URI path.
So when Apache APISIX uses radixtree_uri as the default HTTP router,
there is a confusing scenario (even we can say it's a bug): Let's say
we have two routes, the first one requires the host matches
*.example.com, and the URI path is /anything, And the second one needs
the host matches foo.example.com exactly, and the URI path is also
/anything. In such a case, if we send an API request, we may hit the
first route, which is counterintuitive.
We also have a lot of voices from the community that users have been
in trouble since they think Apache APISIX will consider the HTTP host
match by default. However, it's not the case. So I'm here to propose
changing the default HTTP router to radixtree_host_uri.
I know this is a broken change, so we may have to do this in 3.x
releases and may not back it port to the 2.15 LTS version.
By the way, the radixtree_uri may have better performance than
radixtree_host_uri, so if we really change the default HTTP router, we
also need to give users a hint that: if they want better performance
or you are making a stress test, you may change the HTTP router back
to the radixtree_uri.
I think to implement the change, we need to close the tasks below:
Coding for changing the default URI, making all the test cases passed
Write docs for claiming the broken change
Write docs for giving users a hint about the performance difference between radixtree_host_uri and radixtree_uri, give them some advice about the performance tuning

As per the investigation, it is found that the possible changes will be in _M.http_init_worker()
Can you please guide me in testing stuff, as I am finding it difficult to understand the test cases?
Where do I have to update the doc for the changes?

@XFarooqi Actually, just change the default value for the setting "http.router" in config-default.yaml, and run all the test cases, fix the failed ones.
Description
Hi, community,
We talked about changing the default HTTP router from
radixtree_uri
toradixtree_host_uri
in the [mailing list](https://lists.apache.org/thread/6kkrdk2bkxmccwho3lk5jz5lrsvbsxgt).
I'll show the content here again:
