The session catalog is the material catalog which provides session attributes for the request, and a default catId value for all src=
, vignette=
, and icc=
commands.
The session catalog is specified as the first path element of the HTTP request path (immediately following the server name). If the first path element does not match attribute::RootId of any catalog, the default catalog is used as a session catalog.
The session catalog provides the following session default values:
