                   9126: 
                   9127: Handles the viewing of grades.
                   9128: 
                   9129: This is part of the LearningOnline Network with CAPA project
                   9130: described at http://www.lon-capa.org.
                   9131: 
                   9132: =head1 OVERVIEW
                   9133: 
                   9134: Do an ssi with retries:
                   9135: While I'd love to factor out this with the vesrion in lonprintout,
                   9136: 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
                   9137: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9138: 
                   9139: At least the logic that drives this has been pulled out into loncommon.
                   9140: 
                   9141: 
                   9142: 
                   9143: ssi_with_retries - Does the server side include of a resource.
                   9144:                      if the ssi call returns an error we'll retry it up to
                   9145:                      the number of times requested by the caller.
                   9146:                      If we still have a proble, no text is appended to the
                   9147:                      output and we set some global variables.
                   9148:                      to indicate to the caller an SSI error occurred.  
                   9149:                      All of this is supposed to deal with the issues described
                   9150:                      in LonCAPA BZ 5631 see:
                   9151:                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
                   9152:                      by informing the user that this happened.
                   9153: 
                   9154: Parameters:
                   9155:   resource   - The resource to include.  This is passed directly, without
                   9156:                interpretation to lonnet::ssi.
                   9157:   form       - The form hash parameters that guide the interpretation of the resource
                   9158:                
                   9159:   retries    - Number of retries allowed before giving up completely.
                   9160: Returns:
                   9161:   On success, returns the rendered resource identified by the resource parameter.
                   9162: Side Effects:
                   9163:   The following global variables can be set:
                   9164:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9165:                               It is up to the caller to initialize this to false
                   9166:                               if desired.
                   9167:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   9168:                               of the resource that could not be rendered by the ssi
                   9169:                               call.
                   9170:    ssi_error_message   - The error string fetched from the ssi response
                   9171:                               in the event of an error.
