                   9589:

                   9594: 
                   9595: Do an ssi with retries:
                   9596: While I'd love to factor out this with the vesrion in lonprintout,
                   9597: 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
                   9598: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9599: 
                   9600: At least the logic that drives this has been pulled out into loncommon.
                   9601: 
                   9602: 
                   9603: 
                   9604: ssi_with_retries - Does the server side include of a resource.
                   9605:                      if the ssi call returns an error we'll retry it up to
                   9606:                      the number of times requested by the caller.
                   9607:                      If we still have a proble, no text is appended to the
                   9608:                      output and we set some global variables.
                   9609:                      to indicate to the caller an SSI error occurred.  
                   9610:                      All of this is supposed to deal with the issues described
                   9611:                      in LonCAPA BZ 5631 see:
                   9612:                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
                   9613:                      by informing the user that this happened.
                   9614: 
                   9615: Parameters:
                   9616:   resource   - The resource to include.  This is passed directly, without
                   9617:                interpretation to lonnet::ssi.
                   9618:   form       - The form hash parameters that guide the interpretation of the resource
                   9619:                
                   9620:   retries    - Number of retries allowed before giving up completely.
                   9621: Returns:
                   9622:   On success, returns the rendered resource identified by the resource parameter.
                   9623: Side Effects:
                   9624:   The following global variables can be set:
                   9625:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9626:                               It is up to the caller to initialize this to false
                   9627:                               if desired.
                   9628:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   9629:                               of the resource that could not be rendered by the ssi
                   9630:                               call.
                   9631:    ssi_error_message   - The error string fetched from the ssi response
                   9632:                               in the event of an error.
