Hi,

I am using Logstash GA 6.3.0. In my Logstash, inside filter, I am checking a url like;

```
filter{
    if [requestUrl] == "/section1/process1" {
        //doing some stuff here
    }
}

```

This is working fine. But this wont filter if `requestUrl` is something like `/section1/process1?query`. How can I do this?

Thanks

Use a regular expression match.

```
if [requestUrl] =~ /^\/section1\/process1/ {

```
