                   9380: 
                   9381: Do an ssi with retries:
                   9382: While I'd love to factor out this with the vesrion in lonprintout,
                   9383: 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
                   9384: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9385: 
                   9386: At least the logic that drives this has been pulled out into loncommon.
                   9387: 
                   9388: 
                   9389: 
                   9390: ssi_with_retries - Does the server side include of a resource.
                   9391:                      if the ssi call returns an error we'll retry it up to
                   9392:                      the number of times requested by the caller.
                   9393:                      If we still have a proble, no text is appended to the
                   9394:                      output and we set some global variables.
                   9395:                      to indicate to the caller an SSI error occurred.  
                   9396:                      All of this is supposed to deal with the issues described
                   9397:                      in LonCAPA BZ 5631 see:

                   9400: 
                   9401: Parameters:
                   9402:   resource   - The resource to include.  This is passed directly, without
                   9403:                interpretation to lonnet::ssi.
                   9404:   form       - The form hash parameters that guide the interpretation of the resource
                   9405:                
                   9406:   retries    - Number of retries allowed before giving up completely.
                   9407: Returns:
                   9408:   On success, returns the rendered resource identified by the resource parameter.
                   9409: Side Effects:
                   9410:   The following global variables can be set:
                   9411:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9412:                               It is up to the caller to initialize this to false
                   9413:                               if desired.
                   9414:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   9415:                               of the resource that could not be rendered by the ssi
                   9416:                               call.
                   9417:    ssi_error_message   - The error string fetched from the ssi response
                   9418:                               in the event of an error.
