If a user needs to use the iConsole within 60 minutes of the iConsole application servers and front-end Web servers being upgraded or a hotfix applied, that user will first need to empty their browser cache to prevent possible Page Errors. For example, to empty the browser cache in Internet Explorer, the user must use the Internet Options dialog to delete all temporary internet files.
This is necessary because JavaScript files required by the iConsole are, by default, cached for one hour on the browser host machine (but see the note below). Consequently, any updated JavaScript files are not available until one hour after the upgrade or hotfix has been applied.
If more than one hour has passed since the upgrade, a user does not need to empty their browser cache before using the iConsole. By then, the JavaScript files required by the iConsole will have been automatically updated. For this reason, we recommend that you roll out iConsole upgrades outside of office hours.
Note: The cache period, or 'content expiration' time, is configurable in Microsoft IIS on the iConsole front-end Web servers. If this cache period has been lengthened beyond one hour (for example, to reduce network traffic), the period during which iConsole users may experience these Page Errors will also be longer. In this situation, you may want to issue a general advisory to your iConsole users asking them to empty their browser caches.
