Hi,

I would like to capture path wildcard regex and use the capture in namespace...  
For example, /path/abc/... to route to namespace 'abc', service: web-server, i.e. web-server.abc. Generalized, this would be /path/(.\*) to web-server.$1 if using the $1 for first regex capture group. There are potentially more complex scenarios, i.e. multiple capture groups.

Is this possible ?  
Thanks ahead

From what I have seen and tried , regex replace will work only on the `path` it self .

```yaml
      replacePathRegex:
        regex: "^/path/(.*)"
        replacement: "/$1"

```

I have tried to achieve something similar to your in past and found out that it was not possible.

In order to achieve what you want , I guess you will need to know all the `(.*)` in advance, in order to have them templated at your `service:` values.  
I guess if its not something that getting spinned-up on the go , you can achieve it by templating your `yamls`.
