                   8945: 
                   8946: Handles the viewing of grades.
                   8947: 
                   8948: This is part of the LearningOnline Network with CAPA project
                   8949: described at http://www.lon-capa.org.
                   8950: 
                   8951: =head1 OVERVIEW
                   8952: 
                   8953: Do an ssi with retries:
                   8954: While I'd love to factor out this with the vesrion in lonprintout,
                   8955: that would either require a data coupling between modules, which I refuse to perpetuate (there's quite enough of that already), or would require the invention of another infrastructure
                   8956: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   8957: 
                   8958: At least the logic that drives this has been pulled out into loncommon.
                   8959: 
                   8960: 
                   8961: 
                   8962: ssi_with_retries - Does the server side include of a resource.
                   8963:                      if the ssi call returns an error we'll retry it up to
                   8964:                      the number of times requested by the caller.
                   8965:                      If we still have a proble, no text is appended to the
                   8966:                      output and we set some global variables.
                   8967:                      to indicate to the caller an SSI error occurred.  
                   8968:                      All of this is supposed to deal with the issues described
                   8969:                      in LonCAPA BZ 5631 see:
                   8970:                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
                   8971:                      by informing the user that this happened.
                   8972: 
                   8973: Parameters:
                   8974:   resource   - The resource to include.  This is passed directly, without
                   8975:                interpretation to lonnet::ssi.
                   8976:   form       - The form hash parameters that guide the interpretation of the resource
                   8977:                
                   8978:   retries    - Number of retries allowed before giving up completely.
                   8979: Returns:
                   8980:   On success, returns the rendered resource identified by the resource parameter.
                   8981: Side Effects:
                   8982:   The following global variables can be set:
                   8983:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   8984:                               It is up to the caller to initialize this to false
                   8985:                               if desired.
                   8986:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   8987:                               of the resource that could not be rendered by the ssi
                   8988:                               call.
                   8989:    ssi_error_message   - The error string fetched from the ssi response
                   8990:                               in the event of an error.
