Is it possible to configure Logstash to remove domain name when receiving URL input?

E.g:

Picture above as an example, I would like to eliminate everthing behind 'path' to send to Elasticsearch. If it is possible, may I get the idea of the configuration?

Using the [standard grok patterns](https://github.com/logstash-plugins/logstash-patterns-core/blob/15e125d10692e93dde76c1a7e28c506ebe62511f/patterns/legacy/grok-patterns#L48) as an example, I would try

```
grok { match => { "yourFieldName" => "%{URIPROTO}://(?:%{USER}(?::[^@]*)?@)?(?:%{URIHOST})?/%{GREEDYDATA:theBitYouWant}" } }
```

Thank you very much! What you suggested is exactly the solution that I was stuck on.
