TTMSMCPHTTPServerResponse.HeaderHasBeenWritten Property

Whether the headers have already been sent. False until they are.

API unit family: TMS.MCP.HTTPServer Declaring type: TTMSMCPHTTPServerResponse Type: Boolean

Syntax

property HeaderHasBeenWritten: Boolean;

Remarks

Set by TTMSMCPHTTPServerResponse.WriteHeader so the server does not send them a second time. Check it before changing the status code or a header; writing to it directly misreports what has actually gone out.
