HTTP response headers over clients

Question

So I am little confused on the behaviour of HTTP headers. My question is:

If I am running an API off a server. If a client makes a request, and i respond to the client via the server by setting a header in the form of:

response.header.<some_header> = <some_value>

will this header persist for all clients (ie some computer, and then another computer, etc), or is this header response unique to the client making the request?

Thanks!!

Answer 1

The response object is only sent to the client that made a request in the first place. In fact you said the answer in your question yourself:

"If a client makes a request, and I respond to the client via the server"

In general if a client made a request, the server can only respond the the client that made the request. Hope this answers your question. For more information on http headers you should read this .
