# Route Security

How to secure routes.

## Limiting Requests

Ask has a built-in limiter that can limit the number of times an IP address can make a request to a specific route during a period of time. E.g. twice a minute, 100 times an hour, etc.

You can limit a route by adding a decorator before the route definition. The decorator takes in as an argument a string with a sort of natural language syntax. You can either use the word *"per"* or a slash (*/*).

```python
# This can only be called from the same IP, once every two minutes.
&limit('1 per 2 minute')
@get('/route1'):
    print('Hello, World!')

# Max 200 request per day from the same IP.
&limit('200/day')
@get('/route2'):
    print('Hello, World!')
```

### Available rules

* Seconds.
* Minutes.
* Hours.
* Days.
* Years

## 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://docs.ask.edvard.dev/security/route-security.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.
