ConnectAsync Method

Sends a non-blocking HTTP/3 CONNECT request; the reply arrives on OnResponse.

Syntax

procedure ConnectAsync(const aURL: string);

Parameters

NameTypeDescription
aURLconst stringAbsolute URL of the target resource.

Return Value

None. The response is delivered on OnResponse.

Remarks

The request runs on a background thread and the method returns immediately. The reply is delivered on OnResponse, and a failure is reported on OnError.

CONNECT requests a tunnel to the target resource. To establish an Extended CONNECT tunnel that stays open, use ExtendedConnect instead.

The synchronous counterpart is Connect, which blocks and returns the body directly.

The events fire on the background worker thread that carried out the request, not on the main thread. Synchronise before touching VCL or FMX controls from the handler.

Example



oClient.OnResponse := OnResponseEvent;

oClient.ConnectAsync('https://api.example.com/v1/items');
