[App Transport Security
(ATS)](https://developer.apple.com/library/prerelease/ios/technotes/App-Transport-Security-Technote/)
is a privacy feature that enforces secure connections. It's enabled by default
for new apps.

The following log message appears when a non-ATS compliant app attempts to serve
an ad using HTTP:
> App Transport Security has blocked a cleartext HTTP (http://)
> resource load since it is insecure. Temporary exceptions can be
> configured in your app's `Info.plist` file.

To disable ATS restrictions, add the following exceptions to your app's
`Info.plist`:

- `NSAllowsArbitraryLoadsForMedia`
- `NSAllowsArbitraryLoadsInWebContent`

```xml
<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoadsForMedia</key>
    <true/>
    <key>NSAllowsArbitraryLoadsInWebContent</key>
    <true/>
</dict>
```

The `NSAllowsArbitraryLoadsForMedia` and `NSAllowsArbitraryLoadsInWebContent`
keys are required to make sure your ads are not impacted by ATS.
