This is passed directly, without 9981: interpretation to lonnet::ssi. 9982: form - The form hash parameters that guide the interpretation of the resource 9983: 9984: retries - Number of retries allowed before giving up completely. 9985: Returns: 9986: On success, returns the rendered resource identified by the resource parameter. 9987: Side Effects: 9988: The following global variables can be set: 9989: ssi_error - If an unrecoverable error occurred this becomes true. 9990: It is up to the caller to initialize this to false 9991: if desired. 9992: ssi_error_resource - If an unrecoverable error occurred, this is the value 9993: of the resource that could not be rendered by the ssi 9994: call. 9995: ssi_error_message - The error string fetched from the ssi response 9996: in the event of an error. 9997: 9998: 9999: =head1 HANDLER SUBROUTINE 10000: 10001: ssi_with_retries() 10002: 10003: =head1 SUBROUTINES 10004: 10005: =over 10006: 10007: =head1 Routines to display previous version of a Task for a specific student 10008: 10009: Tasks are graded pass/fail.
