## RequestContext.requestedProtocol property
Get the protocol used by the client to make the request. Please note this protocol may be different from what we are observing at HTTP/TCP level, because reverse proxies like nginx or sidecars like Envoy are switching between protocols.
**Signature:**
```typescript
get requestedProtocol(): string;
```
