THttpServerResponse Class

Represents the HTTP response being built for a request, exposing the status line, headers, and body content, and controlling how and when the response is sent to the client.

Remarks

Writing to Content sends the response headers automatically the first time body data is produced, after which header-related properties can no longer be changed. When neither ContentLength nor Chunked is set, Sparkle chooses chunked transfer for HTTP/1.1 or closes the connection after the body for HTTP/1.0. Call Close to finish the response.
