Design: Limit Response Sizes

Limiting the response sizes for different classes of users will need to be a configuration parameter. This will be set in the OLFS. Users will initially be divided into two groups: authenticated and unauthenticated. Authenticated users will have unlimited access capability while unauthenticated users will only be allowed to transfer up to N bytes of data.

OLFS and BES communication

Use a SetContext element in the GetData request.

libdap implementation

In the class DDS add set_ and get_response_limit() methods. The set-response_limit() method will be called by the BES in the void BESDataResponseHandler::execute( BESDataHandlerInterface &dhi ) or equivalent method.

In the libdap:ResponseBuilder class
