                   9958: 
                   9959: Do an ssi with retries:
                   9960: While I'd love to factor out this with the vesrion in lonprintout,
                   9961: 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
                   9962: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9963: 
                   9964: At least the logic that drives this has been pulled out into loncommon.
                   9965: 
                   9966: 
                   9967: 
                   9968: ssi_with_retries - Does the server side include of a resource.
                   9969:                      if the ssi call returns an error we'll retry it up to
                   9970:                      the number of times requested by the caller.
                   9971:                      If we still have a proble, no text is appended to the
                   9972:                      output and we set some global variables.
                   9973:                      to indicate to the caller an SSI error occurred.  
                   9974:                      All of this is supposed to deal with the issues described
                   9975:                      in LonCAPA BZ 5631 see:
                   9976:                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
                   9977:                      by informing the user that this happened.
                   9978: 
                   9979: Parameters:
                   9980:   resource   - The resource to include.  This is passed directly, without
                   9981:                interpretation to lonnet::ssi.
                   9982:   form       - The form hash parameters that guide the interpretation of the resource
                   9983:                
                   9984:   retries    - Number of retries allowed before giving up completely.
                   9985: Returns:
                   9986:   On success, returns the rendered resource identified by the resource parameter.
                   9987: Side Effects:
                   9988:   The following global variables can be set:
                   9989:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9990:                               It is up to the caller to initialize this to false
                   9991:                               if desired.
                   9992:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   9993:                               of the resource that could not be rendered by the ssi
                   9994:                               call.
                   9995:    ssi_error_message   - The error string fetched from the ssi response
                   9996:                               in the event of an error.
