Abstract
A browser having a cache protects sensitive information. A browser having a cache and a removal object is opened on a workstation. The browser receives sensitive data into the cache as a web page having a URL identifier. A designation of identifiers having sensitive data is entered into the removal object. Upon termination of a browser session or upon command the removal object is activated to selectively remove the sensitive data from the cache by using the designation.
