# Capturing Web Request Details

By default, the following web request details are masked as they can contain sensitive data:

- Headers
- Server Variables
- Session Variables
- Cookies

However, you can configure your app to unmask any of these in your app's config file. Stackify will then retrieve information about these fields and list it in the Error Details page or in the "View Document" view for an error in your apps. To enable this, you will want to add the following keys into the appSettings section of your App/Web.config:

```
<appSettings>
    <add key="Stackify.CaptureErrorHeaders" value="true" />
    <add key="Stackify.CaptureServerVariables" value="true" />
    <add key="Stackify.CaptureSessionVariables" value="true" />
    <add key="Stackify.CaptureErrorCookies" value="true" />
</appSettings>
```
