This is passed directly, without 10988: interpretation to lonnet::ssi. 10989: form - The form hash parameters that guide the interpretation of the resource 10990: 10991: retries - Number of retries allowed before giving up completely. 10992: Returns: 10993: On success, returns the rendered resource identified by the resource parameter. 10994: Side Effects: 10995: The following global variables can be set: 10996: ssi_error - If an unrecoverable error occurred this becomes true. 10997: It is up to the caller to initialize this to false 10998: if desired. 10999: ssi_error_resource - If an unrecoverable error occurred, this is the value 11000: of the resource that could not be rendered by the ssi 11001: call. 11002: ssi_error_message - The error string fetched from the ssi response 11003: in the event of an error. 11004: 11005: 11006: =head1 HANDLER SUBROUTINE 11007: 11008: ssi_with_retries() 11009: 11010: =head1 SUBROUTINES 11011: 11012: =over 11013: 11014: =head1 Routines to display previous version of a Task for a specific student 11015: 11016: Tasks are graded pass/fail.

By default, the current version is displayed.
