# HTML Clear Data
This action clears cookies, session data and resource cache associated with HTML Control.
Action available for the following operating systems:
### Parameters
* **HTML Control** *\ -* The HTML control to clear the data.
{% hint style="info" %}
Although an HTML control is selected in this action, this actually clears global application cookies, session data and resource cache, since this kind of information is normally stored by the system on application associated data and not on a specific HTML control.
{% endhint %}
{% hint style="info" %}
This action is usefull to clear data stored from previous sessions. For example a user logs on to a service/site using the HTML Control, the system will store session data, and the next time you try to access the same service/site the logon may be reused due to this session data. In this case you can call this action to clear this kind of data, so the user needs to logon again.
{% endhint %}
