Performance Optimization by Disabling Audio Handler

This help article describes how to improve the performance of your ASP.NET application by disabling the RadCaptcha audio handler.

RadCaptcha provides the functionality to request audio for the capthca rendered. You can read more about it in the Using Audio Code article.

This feature is available by using a built-in handler for the audio. Which is available with disabled Audio Code feature and also without using RadCaptcha on the page. In order to eliminate possible requests for the audio, you can set the CaptchaDenyAudioHandler key to true in the web.config file.

Example 1: Disabling audio handler using the CaptchaDenyAudioHandler key.

<add key="Telerik.Web.CaptchaDenyAudioHandler" value="true"/>
