Cookie Sharing Between Browser Instances and iLO
iLO uses browser session cookies in part to distinguish separate logins—each
browser window displays as a separate user login—while actually sharing the
same active session with the iLO. These multiple logins can confuse the browser.
This confusion can appear as an iLO issue is a manifestation of typical browser
behavior.
Several processes can cause a browser to open additional windows. Browser
windows opened from within an open browser represent different aspects of the
same program in memory. Consequently, each browser window shares properties
with the parent, including cookies.
Shared Instances
When iLO opens another browser window, for example, Remote Console,
Virtual Media, or Help, this window shares the same connection to iLO and the
session cookie.
The iLO Web server makes URL decisions based on each request received. For
example, if a request does not have access rights, it is redirected to the login
page, regardless of the original request. Web server based redirection, selecting
File>New>Window or pressing the Ctrl+N keys, opens a duplicate instance of
the original browser.
Cookie Order Behavior
During login, the login page builds a browser session cookie that links the
window to the appropriate session in the firmware. The firmware tracks browser
logins as separate sessions listed in the Active Sessions section of the iLO Status
page.
For example, when User1 logs in, the Web server builds the initial frames view,
with current user: User1 in the top pane, menu items in the left pane, and page
data in the lower-right pane. As User1 clicks from link to link, only the menu
items and page data are updated.
