                   9355: 
                   9356: Do an ssi with retries:
                   9357: While I'd love to factor out this with the vesrion in lonprintout,
                   9358: 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
                   9359: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9360: 
                   9361: At least the logic that drives this has been pulled out into loncommon.
                   9362: 
                   9363: 
                   9364: 
                   9365: ssi_with_retries - Does the server side include of a resource.
                   9366:                      if the ssi call returns an error we'll retry it up to
                   9367:                      the number of times requested by the caller.
                   9368:                      If we still have a proble, no text is appended to the
                   9369:                      output and we set some global variables.
                   9370:                      to indicate to the caller an SSI error occurred.  
                   9371:                      All of this is supposed to deal with the issues described
                   9372:                      in LonCAPA BZ 5631 see:
                   9373:                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
                   9374:                      by informing the user that this happened.
                   9375: 
                   9376: Parameters:
                   9377:   resource   - The resource to include.  This is passed directly, without
                   9378:                interpretation to lonnet::ssi.
                   9379:   form       - The form hash parameters that guide the interpretation of the resource
                   9380:                
                   9381:   retries    - Number of retries allowed before giving up completely.
                   9382: Returns:
                   9383:   On success, returns the rendered resource identified by the resource parameter.
                   9384: Side Effects:
                   9385:   The following global variables can be set:
                   9386:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9387:                               It is up to the caller to initialize this to false
                   9388:                               if desired.
                   9389:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   9390:                               of the resource that could not be rendered by the ssi
                   9391:                               call.
                   9392:    ssi_error_message   - The error string fetched from the ssi response
                   9393:                               in the event of an error.
