If you don't know why you would need this feature, then you don't need it. Leave the default settings alone and ignore them.

Since the primary use case for this feature involves the forwarding or delegation of signed assertions, the XML is passed along unmodified from the issuer. As a result, although some security checking has been performed prior to caching, the data itself is left alone. Attribute filtering is not reflected in the results. |
When In order for the export to be functional, the exportLocation and exportACL properties must be set for the relevant application's <Sessions> element. In addition, the <SessionCache> element must either omit, or turn on the cacheAssertions property. It defaults on, but may be explicitly turned off to optimize the cache when assertions don't need to be accessed later.
Then, when instructed to do so for a request (via the exportAssertion content setting), the application will be given a header or variable called Shib-Assertion-Count with the number of assertions that are available.
The URL to query for each assertion is passed in an individual header or variable named Shib-Assertion-NN, where NN is the two-digit sequence number of the assertion(01, 02, etc). Performing a GET on that location will result in the assertion, with a MIME type of "application/samlassertion+xml".Note that in order for export to occur, the exportLocation and exportACL properties must be set for the relevant application's <Sessions> element

Distributed Scenarios
In some cases, it's possible for the code that needs to perform the retrieval to be running on a different host from the SP itself. One such scenario would be a Java container fronted by Apache, such that Apache and the SP run separately from the Java container. The SP doesn't provide any real way of "securing" the retrieval step.
