How to send data from the form to the mail, and to another page with a get request?

Question

URL Handling

It is necessary that an email be sent from the feedback form. Many scripts can do this. Apart from sending it to the mail, this is also elementary - method="get" action="required page". But I don’t understand how to form a GET to another page and send a letter to the mail.

Example
https://zvezdny-taxi.ru/novosibirsk

Answer 1

Or maybe just a script with sendmail and send another request? Then this Get will not be seen by the sender user.
