This is passed directly, without 10813: interpretation to lonnet::ssi. 10814: form - The form hash parameters that guide the interpretation of the resource 10815: 10816: retries - Number of retries allowed before giving up completely. 10817: Returns: 10818: On success, returns the rendered resource identified by the resource parameter. 10819: Side Effects: 10820: The following global variables can be set: 10821: ssi_error - If an unrecoverable error occurred this becomes true. 10822: It is up to the caller to initialize this to false 10823: if desired. 10824: ssi_error_resource - If an unrecoverable error occurred, this is the value 10825: of the resource that could not be rendered by the ssi 10826: call. 10827: ssi_error_message - The error string fetched from the ssi response 10828: in the event of an error. 10829: 10830: 10831: =head1 HANDLER SUBROUTINE 10832: 10833: ssi_with_retries() 10834: 10835: =head1 SUBROUTINES 10836: 10837: =over 10838: 10839: =head1 Routines to display previous version of a Task for a specific student 10840: 10841: Tasks are graded pass/fail.
