                   9470:

                   9474: =head1 OVERVIEW
                   9475: 
                   9476: Do an ssi with retries:
                   9477: While I'd love to factor out this with the vesrion in lonprintout,
                   9478: 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
                   9479: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9480: 
                   9481: At least the logic that drives this has been pulled out into loncommon.
                   9482: 
                   9483: 
                   9484: 
                   9485: ssi_with_retries - Does the server side include of a resource.
                   9486:                      if the ssi call returns an error we'll retry it up to
                   9487:                      the number of times requested by the caller.
                   9488:                      If we still have a proble, no text is appended to the
                   9489:                      output and we set some global variables.
                   9490:                      to indicate to the caller an SSI error occurred.  
                   9491:                      All of this is supposed to deal with the issues described
                   9492:                      in LonCAPA BZ 5631 see:
                   9493:                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
                   9494:                      by informing the user that this happened.
                   9495: 
                   9496: Parameters:
                   9497:   resource   - The resource to include.  This is passed directly, without
                   9498:                interpretation to lonnet::ssi.
                   9499:   form       - The form hash parameters that guide the interpretation of the resource
                   9500:                
                   9501:   retries    - Number of retries allowed before giving up completely.
                   9502: Returns:
                   9503:   On success, returns the rendered resource identified by the resource parameter.
                   9504: Side Effects:
                   9505:   The following global variables can be set:
                   9506:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9507:                               It is up to the caller to initialize this to false
                   9508:                               if desired.
                   9509:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
