# AppServer

Review the new B2C Commerce AppServer feature in the 20.6 release.

- **[Verify User Permissions for New Stricter WebDAV Zip Check](https://help.salesforce.com/s/articleView?id=commerce.b2c_20_6_w7623312_webdav_perms_la.htm&release=264.0.0&type=5)**  
    B2C Commerce supports an extension to the WebDAV protocol that allows a client to pack files and folders into a zip archive at the server. With this release, the permission check for creating WebDAV zip archives is stricter.
- **[Set Access Restrictions for Uploading Code by August 1, 2020](https://help.salesforce.com/s/articleView?id=commerce.b2c_20_6_w7718774_access_restrictions_la.htm&release=264.0.0&type=5)**  
    For security reasons, you must disallow code uploads to production instances and require a client certificate for code uploads to staging instances. We mandated this configuration by April 1, 2020, but did not start proactive enforcement because of COVID-19. As of August 1, 2020, we will start proactive enforcement.
