# Check Links before Clicking or Using Them

{% hint style="warning" %}

### Prerequisite

URL filtering must be enabled in the Malware prevention profile for iOS devices.
{% endhint %}

The Cortex XDR app lets you test any URL, using the new **Share** option. You can safely select the link and share it by selecting the option **Validate URL with Cortex XDR**. The link will be diagnosed with the Palo Alto Advanced URL Filtering engine, and you will receive an informative summary page about the result of the test. This summary will include information such as whether the link is malicious or not, and the associated site categories and risk level.

1. Share the link, and then select the **Validate URL with Cortex XDR** option.
2. After you receive the test results from Cortex XDR, decide whether you want to click, use, or share the link, or not.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xdr-agent-ios-guide/9.2/device-user-tasks/check-links-before-clicking-or-using-them.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
