The "XML Backup" and "XML Restore" functions each have their own HTTP requests. After the
reader has received one of these HTTP requests, if the requirements have been met, the
following tasks are first performed in both cases:
1. The connection to the WBM is terminated.
While the HTTP request is being processed by the optical reader, you can only open the
WBM in READ ONLY mode.
2. The optical reader changes to "Stop" mode.
3. The IN_OP bit is set to "0".
9.8.2 XML backup
Once the optical reader has sent the HTTP response, the "IN_OP" bit is set and access via the
WBM is permitted again.
Request
Stucture and properties of the request:
• URI: http://<IP address of the optical reader>/xml/backup.cgi
e.g. http://192.168.0.42/xml/backup.cgi
• HTTP method: GET
Response
