Location header is lost if max-redirects > 1


Location header is lost if max-redirects > 1

around this issue Apparently I misunderstood the Location header. It comes with redirect response, so when I set up max-redirect > 0 and I have a redirect I get the latest response that is already redirected and it does not have a Location header. Spray's HttpResponse is not coupled to immediate request that generated it, so there is no way to figure out what was the URL from which this response came. My solution is to do a manual redirection.

Does that help After fighting with your regex an thinking of the use case... I think you would probably can do a much straightforward thing, such as rewrite the location and cache the object corrected (and leave redirection to client browser).
On vcl_fetch:
code :
# ...
if ( beresp.status == 301
  || beresp.status == 302
) {
  # Check if we're redirecting to a different site
  if ( ! beresp.http.Location ~ req.http.host ) {
    # Rewrite HTTP Location header to cache it and pass redirection to client
    set beresp.http.Location = regsub(
                                 beresp.http.Location,
                                 "^http://[^/]+/",
                                 "http://" + req.http.host + "/"
                               );
  }
}
# ...
# ...
if ( beresp.status == 301
  || beresp.status == 302
) {
  # Add a header so you can debug cleanly on varnishlog
  set req.http.X-Redirected-Orig = beresp.http.Location;
  # Rewrite request host
  set req.http.host = regsub(
                        regsub(
                          beresp.http.Location,
                          "^http://",
                          "",
                        ),
                        "^([^/]+)/.*$",
                        "\1"
                      );
  # Rewrite request url
  set req.url = regsub(
                  beresp.http.Location,
                  "^http://[^/]+/(.*)$",
                  "/\1",
                );
  # Add a header so you can debug cleanly on varnishlog
  set req.http.X-Redirected-To = "http://" + req.http.host + req.url;
  return (restart);
}

$_SESSION values lost after a header('Location: .........')

hop of those help? You called session_destroy() then set more sessions, so you need to make sure session_start() is called again before resetting the sessions. Or don't call session_destroy at all.
Like so:
code :
$login      = $_SESSION['login'];
$statut     = $_SESSION['statut'];
$atelier    = $_SESSION['atelier'];
$connexion  = $_SESSION['connexion'];

// session_destroy (); - unnecessary

$_SESSION['login']      = $login;
$_SESSION['statut']     = $statut;
$_SESSION['atelier']    = $atelier;
$_SESSION['connexion']  = true;
header('Location: http://10.13.48.60/no_serie.php');

With these it helps This is not explicitly stated in the documentation, but requests only follows redirects (automatically, or if instructed to do so via allow_redirects=True) - but not every response with a Location header necessarily is a redirect.
code :
@property
def is_redirect(self):
    """True if this Response is a well-formed HTTP redirect that could have
    been processed automatically (by :meth:`Session.resolve_redirects`).
    """
    return ('location' in self.headers and self.status_code in REDIRECT_STATI)

With these it helps header('location: ./') don't use this instead use header('location:/')
