This is passed directly, without 10427: interpretation to lonnet::ssi. 10428: form - The form hash parameters that guide the interpretation of the resource 10429: 10430: retries - Number of retries allowed before giving up completely. 10431: Returns: 10432: On success, returns the rendered resource identified by the resource parameter. 10433: Side Effects: 10434: The following global variables can be set: 10435: ssi_error - If an unrecoverable error occurred this becomes true. 10436: It is up to the caller to initialize this to false 10437: if desired. 10438: ssi_error_resource - If an unrecoverable error occurred, this is the value 10439: of the resource that could not be rendered by the ssi 10440: call. 10441: ssi_error_message - The error string fetched from the ssi response 10442: in the event of an error. 10443: 10444: 10445: =head1 HANDLER SUBROUTINE 10446: 10447: ssi_with_retries() 10448: 10449: =head1 SUBROUTINES 10450: 10451: =over 10452: 10453: =head1 Routines to display previous version of a Task for a specific student 10454: 10455: Tasks are graded pass/fail.
