As the Gateway component provides secure access to back end corporate data from any location using just a web browser, it may be necessary that the information not be cached locally by the client.
You can disable caching of pages redirected through the Gateway by modifying the attribute in the platform.conf file of the specific Gateway.
Disabling this option can have an impact on the Gateway performance. Every time the standard Portal Desktop is refreshed, the Gateway has to retrieve everything referenced by the page, such as images which may have been previously cached by the browser. However, by enabling this feature, remotely accessing secure content will not leave a cached footprint on the client site. This could outweigh performance implications if the corporate network is being accessed from an Internet cafe or similar remote location that is not under corporate IT control.
Login as root and edit the platform.conf file of the required Gateway instance:
/etc/opt/SUNWportal/platform.conf.gateway-profile-name |
Edit the following line:
gateway.allow.client.caching=true |
This value is set to true by default. Change the value to false to disable browser caching at the client side.
Restart the Gateway:
./psadmin start-sra-instance –u amadmin – f <password file> –N <profile name>– t <gateway>
