                   9681: 
                   9682: Do an ssi with retries:
                   9683: While I'd love to factor out this with the vesrion in lonprintout,
                   9684: 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
                   9685: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9686: 
                   9687: At least the logic that drives this has been pulled out into loncommon.
                   9688: 
                   9689: 
                   9690: 
                   9691: ssi_with_retries - Does the server side include of a resource.
                   9692:                      if the ssi call returns an error we'll retry it up to
                   9693:                      the number of times requested by the caller.
                   9694:                      If we still have a proble, no text is appended to the
                   9695:                      output and we set some global variables.
                   9696:                      to indicate to the caller an SSI error occurred.  
                   9697:                      All of this is supposed to deal with the issues described
                   9698:                      in LonCAPA BZ 5631 see:

                   9701: 
                   9702: Parameters:
                   9703:   resource   - The resource to include.  This is passed directly, without
                   9704:                interpretation to lonnet::ssi.
                   9705:   form       - The form hash parameters that guide the interpretation of the resource
                   9706:                
                   9707:   retries    - Number of retries allowed before giving up completely.
                   9708: Returns:
                   9709:   On success, returns the rendered resource identified by the resource parameter.
                   9710: Side Effects:
                   9711:   The following global variables can be set:
                   9712:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9713:                               It is up to the caller to initialize this to false
                   9714:                               if desired.
                   9715:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   9716:                               of the resource that could not be rendered by the ssi
                   9717:                               call.
                   9718:    ssi_error_message   - The error string fetched from the ssi response
                   9719:                               in the event of an error.
