com.opensymphony.oscache.web.tag.UseCachedTag
UseCachedTag is a tag that tells a <cache> tag to reuse the cached body.
Usage Example:
<%@ taglib uri="oscache" prefix="cache" %>
<cache:cache key="mycache" scope="application">
if (reuse cached)
<cache:usecached />
else
some other logic
</cache:cache>
Note this is very useful with try / catch blocks
so that you can still produce old cached data if an
exception occurs, eg your database goes down.
