| Request Information, accessible to server-side request interceptors.
Some attributes and operations on ServerRequestInfo are not
valid at all interception points. The following table shows the validity
of each attribute or operation. If it is not valid, attempting to access
it will result in a BAD_INV_ORDER being thrown with a
standard minor code of 14.

- When
ServerRequestInfo is passed to
receive_request, there is an entry in the list for
every argument, whether in, inout, or out. But only the in and
inout arguments will be available.
- If the
reply_status attribute is not
LOCATION_FORWARD, accessing this attribute will throw
BAD_INV_ORDER with a standard minor code of 14.
- If the servant locator caused a location forward, or thrown an
exception, this attribute/operation may not be available in this
interception point.
NO_RESOURCES with a standard minor
code of 1 will be thrown if it is not available.
- The operation is not available in this interception point because
the necessary information requires access to the target object's
servant, which may no longer be available to the ORB. For example,
if the object's adapter is a POA that uses a
ServantLocator, then the ORB invokes the interception
point after it calls ServantLocator.postinvoke() .
