- `apisix.router.http`: The HTTP request route. It can take the following
values:
- - `radixtree_uri`: (Default) Only use the `uri` as the primary index. To
learn more about the support for full and deep prefix matching, check [How to
use router-radixtree](../router-radixtree.md).
+ - `radixtree_uri`: Only use the `uri` as the primary index. To learn more
about the support for full and deep prefix matching, check [How to use
router-radixtree](../router-radixtree.md).
- `Absolute match`: Match completely with the given `uri` (`/foo/bar`,
`/foo/glo`).
- `Prefix match`: Match with the given prefix. Use `*` to represent the
given `uri` for prefix matching. For example, `/foo*` can match with `/foo/`,
`/foo/a` and `/foo/b`.
- `match priority`: First try an absolute match, if it didn't match, try
prefix matching.
- `Any filter attribute`: This allows you to specify any Nginx built-in
variable as a filter, such as URL request parameters, request headers, and
cookies.
- `radixtree_uri_with_parameter`: Like `radixtree_uri` but also supports
parameter match.
- - `radixtree_host_uri`: Matches both host and URI of the request. Use `host
+ uri` as the primary index (based on the `radixtree` engine).
+ - `radixtree_host_uri`: (Default) Matches both host and URI of the request.
Use `host + uri` as the primary index (based on the `radixtree` engine).
+
+:::note
+
+In version 3.2 and earlier, APISIX used `radixtree_uri` as the default Router.
`radixtree_uri` has better performance than `radixtree_host_uri`, so if you
have higher performance requirements and can live with the fact that
`radixtree_uri` only matches uri, consider continuing to use `radixtree_uri` as
the default Router.
Review Comment:
Only use the `uri` as the primary index, not only matches uri
