Passing your data in HTTP headers in response to an Ajax request - how?

Question

PHP

From the server, in addition to the main content in the response to the Ajax request, can I also send my additional HTTP headers for their further use in JavaScript?

For example: I have an HTML page, an Ajax request to a PHP script is made in the JavaScript code. The PHP script issues some additional HTTP header through the header() function, and I use it in JavaScript.

Is there an example of such an interaction?

What HTTP headers can I use for my purposes - ie. to pass from PHP the data I need to JavaScript in addition to the main response to the request?

Answer 1

The meaning is a bit incomprehensible, but you can take something like X-Data-blablabla.
Headers can be retrieved via getAllResponseHeaders()

Answer 2

You can use all the headers that are described in the RFC HTTP
https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
Also for a request with a custom HTTP request name, take a look here:
https://developer. mozilla.org/en-US/docs/Web/HTTP/...
Yes, and in general, get acquainted with
https://developer.mozilla.org/en/docs/Web/HTTP/%D0...
There are plenty of examples when googling "ajax custom request".

Answer 3

you can. For example, header('Content-type: application/json');

Answer 4

those. if I understand correctly, I can send my own HTTP header from PHP and read it safely through getResponseHeader. What is the best name for your title? Are there any restrictions? Rules?
