                   9814: 
                   9815: Do an ssi with retries:
                   9816: While I'd love to factor out this with the vesrion in lonprintout,
                   9817: 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
                   9818: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9819: 
                   9820: At least the logic that drives this has been pulled out into loncommon.
                   9821: 
                   9822: 
                   9823: 
                   9824: ssi_with_retries - Does the server side include of a resource.
                   9825:                      if the ssi call returns an error we'll retry it up to
                   9826:                      the number of times requested by the caller.
                   9827:                      If we still have a proble, no text is appended to the
                   9828:                      output and we set some global variables.
                   9829:                      to indicate to the caller an SSI error occurred.  
                   9830:                      All of this is supposed to deal with the issues described
                   9831:                      in LonCAPA BZ 5631 see:

                   9833:                      by informing the user that this happened.
                   9834: 
                   9835: Parameters:
                   9836:   resource   - The resource to include.  This is passed directly, without
                   9837:                interpretation to lonnet::ssi.
                   9838:   form       - The form hash parameters that guide the interpretation of the resource
                   9839:                
                   9840:   retries    - Number of retries allowed before giving up completely.
                   9841: Returns:
                   9842:   On success, returns the rendered resource identified by the resource parameter.
                   9843: Side Effects:
                   9844:   The following global variables can be set:
                   9845:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9846:                               It is up to the caller to initialize this to false
                   9847:                               if desired.
                   9848:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   9849:                               of the resource that could not be rendered by the ssi
                   9850:                               call.
                   9851:    ssi_error_message   - The error string fetched from the ssi response
                   9852:                               in the event of an error.
