=> A limited number of session ports must be shared by
all public users of Library of Congress Authorities.
To assure that ports are always available, sessions which
are inactive for more than 5 minutes are automatically disconnected.
=>After 5 minutes of inactivity, users will receive a
message that their Session Has Timed Out and that they
must "Start Over."
Session Time-Out Errors
Some users find that their attempts to restart a authorities catalog
session result in a "timed-out" error message. This happens
when a user's Internet browser preferences have been set to prohibit
the reloading (and refreshing) of Web pages that have been previously
visited and stored in its cache.
The authorities catalog assigns a new ID number to each search
session. If a browser prohibits the reloading (and refreshing) of
a Web page, it is unable to update the session ID and will return
When a session times out (and the browser is set to "never reload")
and "restart" is selected, Library of Congress Authorities
will attempt to reload the earlier session. Since the ID attached
to that session indicates the session has timed out, the user always
gets back the message that this session has timed out, and no new
search can be initiated.
Fortunately, it is easy to fix this problem. The user must change
the default settings on the browser to allow new versions of Web
pages to be loaded. The process is slightly different for Internet
Explorer and Netscape.
Because there are many versions of each browser in use, the
exact location and the text of each menu choice in your browser
may be different from those in these instructions.
Internet Explorer Users (assumes version 5.x):
The setting is called "Check for newer versions of stored pages."
- Starting in the Tools menu at the top of the screen, select:
Tools > Internet Options > Temporary Internet Files - Settings
- Under "Check for newer versions of stored pages", select:
Netscape Users (assumes version 4.5/4.7):
The setting is called "Document in cache is compared to document
- Starting in the Edit menu at the top of the screen, select:
Edit > Preferences > Advanced > Cache
- Under "Document in cache is compared to document on network",
IF THE PROBLEM PERSISTS...
If the above steps do not clear up the problem, you can usually
force a server reload of the search page by holding down the
[Shift] key while clicking Reload in Netscape,
or by pressing [CTRL][F5] in MS Internet Explorer.
