This is passed directly, without 11761: interpretation to lonnet::ssi. 11762: form - The form hash parameters that guide the interpretation of the resource 11763: 11764: retries - Number of retries allowed before giving up completely. 11765: Returns: 11766: On success, returns the rendered resource identified by the resource parameter. 11767: Side Effects: 11768: The following global variables can be set: 11769: ssi_error - If an unrecoverable error occurred this becomes true. 11770: It is up to the caller to initialize this to false 11771: if desired. 11772: ssi_error_resource - If an unrecoverable error occurred, this is the value 11773: of the resource that could not be rendered by the ssi 11774: call. 11775: ssi_error_message - The error string fetched from the ssi response 11776: in the event of an error. 11777: 11778: 11779: =head1 HANDLER SUBROUTINE 11780: 11781: ssi_with_retries() 11782: 11783: =head1 SUBROUTINES 11784: 11785: =over 11786: 11787: =head1 Routines to display previous version of a Task for a specific student 11788: 11789: Tasks are graded pass/fail.

By default, the current version is displayed.
