we have sporadic lost of session after POST request.
After submitting form using POST the following page creates a new session using session_start() instead of continuing the session.
Thus all POST data and all session data is lost.
This problem seems not depend on browser.
We get this problem after migration to a new server:
Apache 2.4.17 (FreeBSD) OpenSSL/1.0.2
Free BSD 10.1
Apache 2.4.10 (Unix)
Can anyone help please?
