This is passed directly, without 10911: interpretation to lonnet::ssi. 10912: form - The form hash parameters that guide the interpretation of the resource 10913: 10914: retries - Number of retries allowed before giving up completely. 10915: Returns: 10916: On success, returns the rendered resource identified by the resource parameter. 10917: Side Effects: 10918: The following global variables can be set: 10919: ssi_error - If an unrecoverable error occurred this becomes true. 10920: It is up to the caller to initialize this to false 10921: if desired. 10922: ssi_error_resource - If an unrecoverable error occurred, this is the value 10923: of the resource that could not be rendered by the ssi 10924: call. 10925: ssi_error_message - The error string fetched from the ssi response 10926: in the event of an error. 10927: 10928: 10929: =head1 HANDLER SUBROUTINE 10930: 10931: ssi_with_retries() 10932: 10933: =head1 SUBROUTINES 10934: 10935: =over 10936: 10937: =head1 Routines to display previous version of a Task for a specific student 10938: 10939: Tasks are graded pass/fail.
