                   9456: 
                   9457: Do an ssi with retries:
                   9458: While I'd love to factor out this with the vesrion in lonprintout,
                   9459: 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
                   9460: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9461: 
                   9462: At least the logic that drives this has been pulled out into loncommon.
                   9463: 
                   9464: 
                   9465: 
                   9466: ssi_with_retries - Does the server side include of a resource.
                   9467:                      if the ssi call returns an error we'll retry it up to
                   9468:                      the number of times requested by the caller.
                   9469:                      If we still have a proble, no text is appended to the
                   9470:                      output and we set some global variables.
                   9471:                      to indicate to the caller an SSI error occurred.  
                   9472:                      All of this is supposed to deal with the issues described
                   9473:                      in LonCAPA BZ 5631 see:
                   9474:                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
                   9475:                      by informing the user that this happened.
                   9476: 
                   9477: Parameters:
                   9478:   resource   - The resource to include.  This is passed directly, without
                   9479:                interpretation to lonnet::ssi.
                   9480:   form       - The form hash parameters that guide the interpretation of the resource
                   9481:                
                   9482:   retries    - Number of retries allowed before giving up completely.
                   9483: Returns:
                   9484:   On success, returns the rendered resource identified by the resource parameter.
                   9485: Side Effects:
                   9486:   The following global variables can be set:
                   9487:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9488:                               It is up to the caller to initialize this to false
                   9489:                               if desired.
                   9490:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   9491:                               of the resource that could not be rendered by the ssi
                   9492:                               call.
                   9493:    ssi_error_message   - The error string fetched from the ssi response
                   9494:                               in the event of an error.
