                   11681: Do an ssi with retries:

1.531     jms      11683: 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
                   11684: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   11685: 
                   11686: At least the logic that drives this has been pulled out into loncommon.

                   11690: ssi_with_retries - Does the server side include of a resource.
                   11691:                      if the ssi call returns an error we'll retry it up to
                   11692:                      the number of times requested by the caller.
1.715     bisitz   11693:                      If we still have a problem, no text is appended to the
1.531     jms      11694:                      output and we set some global variables.
                   11695:                      to indicate to the caller an SSI error occurred.  
                   11696:                      All of this is supposed to deal with the issues described
1.715     bisitz   11697:                      in LON-CAPA BZ 5631 see:

                   11703:                interpretation to lonnet::ssi.
                   11704:   form       - The form hash parameters that guide the interpretation of the resource
                   11705:                
                   11706:   retries    - Number of retries allowed before giving up completely.
                   11707: Returns:
                   11708:   On success, returns the rendered resource identified by the resource parameter.
                   11709: Side Effects:
                   11710:   The following global variables can be set:

                   11712:                               It is up to the caller to initialize this to false
                   11713:                               if desired.
                   11714:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   11715:                               of the resource that could not be rendered by the ssi
                   11716:                               call.
                   11717:    ssi_error_message   - The error string fetched from the ssi response
                   11718:                               in the event of an error.
