# Script execution sequence

All `onRequest` and `onResponse` scripts are executed in sequence. First, the `onRequest` scripts are executed from the top down, then the `onResponse` scripts are executed from the bottom up.

```
client -> filter 1 onRequest -> filter 2 onRequest -> resource
client <- filter 1 onResponse <- filter 2 onResponse <- resource
```

The following sample router configuration *(tooltip: You can edit the router configuration over REST at the config/router endpoint.)* shows the order in which the scripts would be executed:

```json
{
    "filters" : [
        {
            "onRequest" : {
                "type" : "text/javascript",
                "source" : "require('router-authz').testAccess()"
            }
        },
        {
            "pattern" : "^managed/realm-name_user",
            "methods" : [
                "read"
            ],
            "onRequest" : {
                "type" : "text/javascript",
                "source" : "console.log('requestFilter 1');"
            }
        },
        {
            "pattern" : "^managed/realm-name_user",
            "methods" : [
                "read"
            ],
            "onResponse" : {
                "type" : "text/javascript",
                "source" : "console.log('responseFilter 1');"
            }
        },
        {
            "pattern" : "^managed/realm-name_user",
            "methods" : [
                "read"
            ],
            "onRequest" : {
                "type" : "text/javascript",
                "source" : "console.log('requestFilter 2');"
            }
        },
        {
            "pattern" : "^managed/realm-name_user",
            "methods" : [
                "read"
            ],
            "onResponse" : {
                "type" : "text/javascript",
                "source" : "console.log('responseFilter 2');"
            }
        }
    ]
}
```

This configuration would produce a log as follows:

```none
requestFilter 1
requestFilter 2
responseFilter 2
responseFilter 1
```
