Using Browser Cache Management
Use Browser Cache Management to improve client side performance and security of IBM® Lotus® iNotes™ sessions on Microsoft® Internet Explorer by controlling which entries are stored in the cache and which are removed when the Lotus iNotes session ends. Many organizations restrict files that are left in the browser cache for security reasons but for lower end machines, loading the Lotus iNotes for each session may adversely impact performance. So, for example, you may want to leave Lotus iNotes design elements in the cache for performance reasons, but remove everything retrieved from mail files for security reasons.

You can set the cache scrubbing level to remove all cache entries or only those related to the user’s mail file. Browser Cache Management improves client side performance, for example, by archiving static design elements of Lotus iNotes locally, and then restoring them to the cache the next time the browser is accessed. This is particularly useful when Lotus iNotes is accessed via a lower bandwidth connection.

Setting up Browser Cache Management

You set up Browser Cache Management in the Lotus iNotes server’s Configuration Settings document. Once you have enabled this feature, you can choose whether to install it on Lotus iNotes clients automatically, or to give users the option of installing it. If you install it automatically, the first time a user accesses Lotus iNotes, a Browser Cache Management system confirmation displays, prompting the user to close all browser windows for Browser Cache Management to take effect.

If you enable Browser Cache Management but do not install it automatically, users can install (and uninstall) it using a Lotus iNotes preference (Preferences - Logout). If you have not enabled Browser Cache Management, this preference is not visible. As an additional security measure, you can prevent users who have not installed Browser Cache Management from adding or accessing e-mail attachments.

Once the Browser Cache Management feature has been installed on a user’s system, the cache cleanup occurs based on the cache scrubbing level set in the server’s Configuration Settings document. The user cannot change this. However, if it has not been installed, users can manually clear the cache at logout by clearing the history, and selecting one of these logout options:


Caching STLinks files

By default, Lotus iNotes forces caching of STLinks files. To override this, use the NOTES.INI setting iNotes_WA_DisableExpiresForSTLinks=1.
