# AppServer

Review the new B2C Commerce AppServer features in the 20.7 release.

- **[Monitor Browser Access Patterns and Unexpected Changes](https://help.salesforce.com/s/articleView?id=commerce.b2c_20_7_w7501840_app_server_response_header_la.htm&release=264.0.0&type=5)**  
    You can use the method `dw.system.Response.addHttpHeader` to specify a response header of Content-Security-Policy-Report-Only for storefront requests.
- **[Use Simplified, Consistent File Retention Rules](https://help.salesforce.com/s/articleView?id=commerce.b2c_20_7_w7673164_retention_rules_la.htm&release=264.0.0&type=5)**  
    New file retention rules are available for files in the /Logs, /Securitylogs, /Impex, and /Temp folders. Previously, different folders, instances, and environments used different file retention periods or no retention period at all. The new retention logic will be enabled after the 20.7 release. Download and save files you want to retain for longer than the new retention period.
