RequestContext from a ServletContext, ServletRequest and ServletResponse. Important Note
Before we explain the benefits of creating your own RequestContext please take note that only one instance of this must be created and passed along during a requests life-cycle. In normal circumstances one will be created through the IDACall servlet and there will be no need for you to handle this explicitly.
A typical use case for explicitly creating a RequestContext is is you've implemented your own standalone servlet which does not extend IDACall and you require the servlet request/response to be available further down the request chain such as in a DMI call you might issue from your servlet. This could be useful when passing session related data down to your DMI implementations for instance. Once you've created a RequestContext you simply set it on your DSRequest or RPCRequest using setContext(requestContext).
