TTMSMCPSetCustomHeaderEvent Event Type

Adds headers to an answer before it is sent.

API unit family: TMS.MCP.Transport.StreamableHTTP

Remarks

Raised only for requests addressed to the protocol endpoint, and only after one has been handled - not for a rejected request, and not for the discovery or metadata addresses. The status code and body are already decided by this point, so use it to add headers rather than to change the outcome. Runs on a connection thread.

Parameters

Name	Description
Sender	Channel that is answering.
ARequest	The request being answered, for deciding what to add.
AResponse	The answer. Add headers with TTMSMCPHTTPServerHeaders.SetHeader or TTMSMCPHTTPServerHeaders.AddValue.
