1.531     jms      10645: 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
                   10646: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   10647: 
                   10648: At least the logic that drives this has been pulled out into loncommon.

                   10653:                      if the ssi call returns an error we'll retry it up to
                   10654:                      the number of times requested by the caller.
1.715     bisitz   10655:                      If we still have a problem, no text is appended to the
1.531     jms      10656:                      output and we set some global variables.
                   10657:                      to indicate to the caller an SSI error occurred.  
                   10658:                      All of this is supposed to deal with the issues described

                   10669: Returns:
                   10670:   On success, returns the rendered resource identified by the resource parameter.

                   10674:                               It is up to the caller to initialize this to false
                   10675:                               if desired.
                   10676:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   10677:                               of the resource that could not be rendered by the ssi
                   10678:                               call.
                   10679:    ssi_error_message   - The error string fetched from the ssi response
