Maintaining Files
- Select Maintain>Files in the J-Web
user interface.
The Files page appears. Table 258 explains the contents of this page.
When you use an HTTPS connection in the Microsoft Internet Explorer browser to save a report from this page in the J-Web interface, the error message "Internet Explorer was not able to open the Internet site" is displayed. This problem occurs because the Cache-Control: no cache HTTP header is added on the server side and Internet Explorer does not allow you to download the encrypted file with the Cache-Control: no cache HTTP header set in the response from the server.
As a workaround, refer to Microsoft Knowledge Base article 323308, which is available at this URL: http://support.microsoft.com/kb/323308. Also, you can alternatively use HTTP in the Internet Explorer browser or use HTTPS in the Mozilla Firefox browser to save a file from this page.
- Click Clean Up Files. The device
rotates log files and identifies the files that can be safely deleted.
The J-Web interface displays the files that you can delete and the amount of space that will be freed on the file system.
- Click one:
- OK — Deletes the files and returns to the Files page.
- Cancel — Cancels your entries and returns to the list of files in the directory.
Enter the information specified in Table 258 to maintain the secure router.
