Use the Browser Access section on the Web Server page of the Options dialog box to configure which browser addresses can view your VI front panels. Create a Browser Access List that allows and denies access to individual browser addresses. You also can use the Web Server:TCP/IP Access List property to allow and deny access to browser addresses programmatically.
When a Web browser attempts to obtain a VI front panel image, the Web Server compares the browser address to the entries in the Browser Access List to determine whether it should grant access. If an entry in the Browser Access List matches the browser address, the Web Server permits or denies access based on how you set up the entry. By default all browsers have access to the LabVIEW Web Server. When you add new Browser Access List entries, edit existing entries, or remove entries, use the correct syntax, order, and wildcards in the entries.
