                   10073: 
                   10074: Handles the viewing of grades.
                   10075: 
                   10076: This is part of the LearningOnline Network with CAPA project
                   10077: described at http://www.lon-capa.org.
                   10078: 
                   10079: =head1 OVERVIEW
                   10080: 
                   10081: Do an ssi with retries:
                   10082: While I'd love to factor out this with the vesrion in lonprintout,
                   10083: 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
                   10084: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   10085: 
                   10086: At least the logic that drives this has been pulled out into loncommon.
                   10087: 
                   10088: 
                   10089: 
                   10090: ssi_with_retries - Does the server side include of a resource.
                   10091:                      if the ssi call returns an error we'll retry it up to
                   10092:                      the number of times requested by the caller.
                   10093:                      If we still have a proble, no text is appended to the
                   10094:                      output and we set some global variables.
                   10095:                      to indicate to the caller an SSI error occurred.  
                   10096:                      All of this is supposed to deal with the issues described
                   10097:                      in LonCAPA BZ 5631 see:
                   10098:                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
                   10099:                      by informing the user that this happened.
                   10100: 
                   10101: Parameters:
                   10102:   resource   - The resource to include.  This is passed directly, without
                   10103:                interpretation to lonnet::ssi.
                   10104:   form       - The form hash parameters that guide the interpretation of the resource
                   10105:                
                   10106:   retries    - Number of retries allowed before giving up completely.
                   10107: Returns:
                   10108:   On success, returns the rendered resource identified by the resource parameter.
                   10109: Side Effects:
                   10110:   The following global variables can be set:
                   10111:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   10112:                               It is up to the caller to initialize this to false
                   10113:                               if desired.
                   10114:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   10115:                               of the resource that could not be rendered by the ssi
                   10116:                               call.
                   10117:    ssi_error_message   - The error string fetched from the ssi response
                   10118:                               in the event of an error.
