Products.Sessions 5.0

Zope session management.

Overview

Zope server side session management.

This package contains Products.Sessions and Products.Transience.

Please note

Before release 5.2 of the tempstorage package sessioning configurations using the simple temporary folder implementation shown below were discouraged because the temporary storage backend could lose data. This is no longer the case.

Using sessions with Zope

For simple RAM memory-based sessioning support, suitable for smaller deployments with a single Zope application server instance, add or uncomment the following temporary storage database definition in your Zope configuration file:

<zodb_db temporary>
    <temporarystorage>
      name Temporary database (for sessions)
    </temporarystorage>
    mount-point /temp_folder
    container-class Products.TemporaryFolder.TemporaryContainer
</zodb_db>

After a Zope restart, visit the Zope Management Interface and select ZODB Mount Point from the list of addable items to instantiate the temporary folder mount point. This only needs to be done once. After that point the temp_folder object will be recreated on each Zope restart and the session support will automatically put a session data container into the temporary folder.

For more advanced scenarios see the Zope book chapter on Session management.

Changelog

5.0 (2023-10-16)

• Add support for Python 3.12.

• Fix the browser ID manager cookie setting for Availability. The name of the cookie flag ws incorrect so it was always False.

• Drop support for Python 2.7, 3.5, 3.6.

4.15 (2022-12-16)

• Fix insidious buildout configuration bug for tests against Zope 4.

4.14 (2022-09-20)

• Add ability to set the session cookie’s SameSite flag. See https://hacks.mozilla.org/2020/08/changes-to-samesite-cookie-behavior/ for some background on how browsers change handling SameSite. The behavior of existing sites will not change unless the site administrator changes the cookie configuration explicitly. New browser id managers will use Lax by default.
