## Settings.experimentalAutoDetectLongPolling property

Configures the SDK's underlying transport (WebChannel) to automatically detect if long-polling should be used. This is very similar to `experimentalForceLongPolling`<!-- -->, but only uses long-polling if required.

This setting will likely be enabled by default in future releases and cannot be combined with `experimentalForceLongPolling`<!-- -->.

<b>Signature:</b>

```typescript
experimentalAutoDetectLongPolling?: boolean;
```
