Perportlet

Perportlet is a term that is not part of the standard vocabulary of portal and portlet technology. In common usage, the relevant concept is a portlet, a modular UI component that renders content within a portal page according to the Java Portlet Specification.

When "perportlet" is encountered, it is usually either a misspelling of "portlet" or a shorthand for ideas that apply to an individual portlet instance. Potential interpretations include per-portlet configuration (settings stored per instance rather than globally), per-portlet state or cache (data isolated to a single portlet), or per-portlet customization (user-specific or page-specific UI variations).

Because there is no formal definition, the meaning depends on the source. If you see "perportlet" in documentation, check whether the author intended "portlet" or a per-instance concept and look for clarifications about scope, persistence, and isolation.
