Display options

By default, the Builtin browser opens with only the title bar, but no navigation bar.
  • To display the navigation bar with additional functions, open the properties of your browser application and click Advanced. (from 15 2101 and eLux® RP 6 2103)
With which functions the navigation bar is displayed, you also define in the Advanced browser settings:
Browser
1 Back
2 Forward
3 Home button to open home page
4 Refresh
5 Address bar
6 Print
The title bar is always shown.

User Agent-String

With each page request, the Builtin browser transmits a 'User Agent' string, which is predefined by the WebKit2 engine. It contains information like Mozilla compatibility and operating system.
To transmit individual information, define an Advanced file entry:
  1. In the Scout Console, for the relevant devices, open Advanced device configuration > Advanced file entries.
    File /setup/sessions.ini
    Section [BuiltinBrowserDefaults]
    Entry UserAgentString
    Value <name/version> <individual string>
    Example Mozilla/5.0 (X11; Linux x86_64)
    For further information, see Advanced file entries.
    Note:
    Name and version must be included in the User Agent string.

DNS cache

from eLux RP 6 2104
The DNS cache of the Builtin browser is set to 120 seconds by default. To configure the timeout value individually, define an environment variable in the Advanced device configuration:
  1. In the Scout Console, for the relevant devices, open Advanced device configuration > Environment.
  2. To define a new variable, click New.
  3. Enter the variable using the format: WEBKIT_DNS_CACHE_EXPIRE_TIMEOUT=<number of seconds> and confirm with OK.
    The new variable is shown in the list.
For further information, see Environment variables.
