Managing the Browser Cache

Some types of Siebel application elements are stored in the browser cache, to improve performance when users log in or access Siebel views.

NOTE:  When measuring performance, you should take into account view layout caching or other types of caching. For example, performance is better when a Siebel view layout is retrieved from a cache than it is when the view layout is not cached and must be retrieved from the system. For more information, see Improving Performance Using View Layout Caching.

Cache usage varies according to what browser is being used, what applications are running, and application settings. For example, high interactivity applications use the browser cache more than standard interactivity applications.

For high interactivity applications, it is generally recommended that users do not clear their browser cache, including when the browser is closed. The following settings for Microsoft Internet Explorer are recommended:

• Choose Tools > Internet Options. Click the Advanced tab. In the Security options, uncheck the setting Empty Temporary Internet Files Folder when browser is closed.

  NOTE:  If you do not use the above setting, then persistent view layout caching and preloading, described in Improving Performance Using View Layout Caching, will not work.

• Choose Tools > Internet Options. Click the Advanced tab. In the Security options, uncheck the setting Do not save encrypted pages to disk.

  NOTE:  If you do not use the above setting, then persistent view layout caching and preloading, described in Improving Performance Using View Layout Caching, will not work for encrypted views (views encrypted using SSL).

• Choose Tools > Internet Options. In the General tab, click Settings. For the option Check for newer versions of stored pages, use the setting Automatically.
• Browser caching is also subject to the size of the temporary Internet files folder. This setting is located in Tools > Internet Options. In the General tab, click Settings, then specify the amount of disk space to use for this folder.

  NOTE:  Setting the size of the temporary Internet files folder to 0 disables persistent view layout caching and preloading, which are described in Improving Performance Using View Layout Caching.

For more information about browser settings for Siebel applications, see Siebel System Administration Guide.

Caching in the browser is also subject to Web server settings controlling static file caching. For details, see Specifying Static File Caching.
