# Manage Capping for Popunders and Fullpage Interstitials
As a Publisher, when you create or edit a Popunder, Desktop Fullpage Interstitial, or Mobile Fullpage Interstitial zone, you can enable or disable **capping** for your ad zone. With this option, you can manage capping (display frequency) on your own side.
**Supported Ad Formats:** Popunder, Mobile Popunder, Desktop Fullpage Interstitial, Mobile Fullpage Interstitial.
## Setting Up
### Step 1: Enable/Disable Capping Through the Snippet
Disable the capping on the Popunder snippet. Set **capping\_enabled** or **ad\_capping\_enabled** to `false` in the ad snippet.
{% code overflow="wrap" expandable="true" %}
```html
```
{% endcode %}
{% code overflow="wrap" expandable="true" %}
```html
```
{% endcode %}
{% hint style="info" %}
**Note**: Complete Step 2 and Step 3 to ensure the ad is not triggered on every click.
{% endhint %}
### Step 2: Setting Up Event Listener
Set up the event listener for the `creativeDisplayed` event so that you can store and increment the capping counter on your own side.
{% code overflow="wrap" expandable="true" %}
```html
```
{% endcode %}
### Step 3: Managing the Page DOM
Based on the value of the counter, which you can store in any way, exclude the snippet from the page DOM. You can do this on the front end or the back end; both examples follow.
FE Example:
{% code expandable="true" %}
```html
Example page
Example link
```
{% endcode %}
BE Example:
{% code expandable="true" %}
```php
Test
Example link
```
{% endcode %}

## 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.exads.com/publishers/sites-and-zones/fpi-popunder-capping-option.md?ask=&goal=
```
`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.
