Do both sites use the same php.ini?

Not sure, I'll check

The hostname is the same?
Yes


Is it a session cookie or a persistent cookie ( I think that a session
cookie depending on browser are not shared between http and https)

Session cookie. If it weren't shared then it would never work but it does
some of the time.

You can use the chrome "Developer Tools" (F12 on chrome) -> resources
-> Cookies to check this out.

Take a look at this page:
http://www.php.net/manual/en/session.configuration.php#ini.session.save-handler
Maybe they aren't sharing the same handler.

But why would this be occasional and not permanent?

Hi
It is mod_php running on apache/Linux and you are right, it is php
that handles the sessions not Apache.

Any ideas?

Hi Robin.

It sounds like it is a platform dependent issue.
As far as i know the sessions storage are handle by
AppServer/Plataform and not by apache itself (Apache only pass the session
cookies to the plataform)

What language/plataform are they using? (PHP, JavaEE, .Net, asp e
etc?)
How does the apache respond to the requests ( A specific Handler,
mod_proxy, a CGI/FastCGI e etc) ?

I've got a client I'm doing some dev work for and they have a website
that spans HTTP and HTTPS and the site needs to pass a session cookie
between both. Ignore the fact that this isn't the best way to do
things, it is a legacy site and there isn't rewrite budget.

The problem I've got is that occasionally the two sides don't appear
to be sharing the same session file on disk so values put in to the
session on the HTTP side are not appearing on the HTTPS side and vise
versa. It isn't consistent and I've not been able to pin down any
pattern when it does it.

The hosting company is a black box who haven't been able to offer
much
help. They say that there is no load balancer in place and that both
the sites are running on the same Apache instance with no special
config beyond the default.

I've put a test script on both sides which displays the current
session id and tries to store and retrieve values, the session ids
match over the two sides so it isn't the browser doing something and
messing those up.

Can anyone suggest anything that could cause this? If the two sides
were consistently unable to share things then I'd put it down to both
using different session files on disk. If it were that a session
created on HTTPS couldn't be seen by HTTP then it could be the secure
flag, but that isn't set.
