                   10642: 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
                   10643: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   10644: 
                   10645: At least the logic that drives this has been pulled out into loncommon.

                   10649: ssi_with_retries - Does the server side include of a resource.
                   10650:                      if the ssi call returns an error we'll retry it up to
                   10651:                      the number of times requested by the caller.
1.596.2.12.2.  8(raebur 10652:4):                      If we still have a problem, no text is appended to the
1.531     jms      10653:                      output and we set some global variables.
                   10654:                      to indicate to the caller an SSI error occurred.  
                   10655:                      All of this is supposed to deal with the issues described

                   10666: Returns:
                   10667:   On success, returns the rendered resource identified by the resource parameter.

                   10671:                               It is up to the caller to initialize this to false
                   10672:                               if desired.
                   10673:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   10674:                               of the resource that could not be rendered by the ssi
                   10675:                               call.
                   10676:    ssi_error_message   - The error string fetched from the ssi response
                   10677:                               in the event of an error.
