AttributesContext

Provides a map for request attributes. When IG processes a single request, it injects transient state information about the request into this context. Attributes stored when processing one request are not accessible when processing a subsequent request.

IG automatically provides access to the attributes field through the attributes bindings in expressions. For example, to access a username with an expression, use ${attributes.credentials.username} instead of ${contexts.attributes.attributes.credentials.username}

Use "SessionContext" to maintain state between successive requests from the same logical client.
