OSCache solves fundamental problems for dynamic websites:
+ Caching Dynamic Content - Dynamic content must often be
executed in some form each request, but sometimes that
content doesn't change every request. Caching the whole
page does not help because sections of the page change
every request. OSCache solves this problem by providing
a means to cache sections of JSP pages.
+ Caching Binary Content - Generated images and PDFs can
be very costly in terms of server load. OSCache solves
this problem through a Servlet 2.3 CachingFilter which
can cache any URI (such as an entire page or a generated
image/PDF)
+ Error Tolerance - If one error occurs somewhere on your
dynamic page, chances are the whole page will be returned
as an error, even if 95% of the page executed correctly.
OSCache solves this problem by allowing you to serve the
cached content in the event of an error, and then
reporting the error appropriately.
