IMAP and NNTP: Improved message cache for newsgroups (R5.0.1)

If you created an IMAP or NNTP account with Notes R5, the design of your proxy database is not automatically updated when you install 5.0.1. The simplest way to make sure you have the latest design is to follow these steps:


How Caching Works

When you open an IMAP or NNTP account, Notes retrieves the message summaries. But now the message summaries are stored in a local cache (actually in the proxy database itself). When you open the same mailbox or newsgroup a second time, Notes does not retrieve the summaries again. The status line at the bottom of Notes will tell you such information as:

"Loaded n messages summaries from cache"

If any new messages have arrived since the last time you visited the mailbox or newsgroup, you should also see:
"Retrieved n message summaries."

If any of the messages have expired since the last time you visited the mailbox or newsgroup, you will see:

"Removed n expired/deleted messages from cache"

Limitations

When you have worked with an IMAP mailbox or NNTP newsgroup for several days, the message summary cache will occasionally get out of synchronization with the remote server. If you suspect this is the case, you can force a complete refresh of the message summaries. For IMAP, click the Refresh action and select the Summaries option. For NNTP, click the Refresh Summaries action.
