How to set sessions for local files?

Question

PHP

Good day to all.
There is an html form in a local file (file:///D:/test/index.html)
via js, it sends a request to an external server ( test.ru/index.php)
if everything is successful - it sends a cookie with the session ( phpsessid=blablabla)
the problem is that I don't see this cookie for a local file, although if you go to test.ru/index.php - the cookie will be saved in the browser (using Chrome)
Is this something to do with cross-domain policy or am I Do I do something wrong / do I understand?
How to solve the problem. thanks for answers

Answer 1

The cookie is only available to scripts on the domain where the cookie was set. That is, on test.ru. You need to set a cookie using JS (eg learn.javascript.ru/cookie) from the form page. If the form will lie on a static site, and all the logic on another, then try using jsonp.
