This is passed directly, without 10954: interpretation to lonnet::ssi. 10955: form - The form hash parameters that guide the interpretation of the resource 10956: 10957: retries - Number of retries allowed before giving up completely. 10958: Returns: 10959: On success, returns the rendered resource identified by the resource parameter. 10960: Side Effects: 10961: The following global variables can be set: 10962: ssi_error - If an unrecoverable error occurred this becomes true. 10963: It is up to the caller to initialize this to false 10964: if desired. 10965: ssi_error_resource - If an unrecoverable error occurred, this is the value 10966: of the resource that could not be rendered by the ssi 10967: call. 10968: ssi_error_message - The error string fetched from the ssi response 10969: in the event of an error. 10970: 10971: 10972: =head1 HANDLER SUBROUTINE 10973: 10974: ssi_with_retries() 10975: 10976: =head1 SUBROUTINES 10977: 10978: =over 10979: 10980: =head1 Routines to display previous version of a Task for a specific student 10981: 10982: Tasks are graded pass/fail.
