                   10580: 
                   10581: Do an ssi with retries:
                   10582: While I'd love to factor out this with the vesrion in lonprintout,
                   10583: 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
                   10584: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   10585: 
                   10586: At least the logic that drives this has been pulled out into loncommon.
                   10587: 
                   10588: 
                   10589: 
                   10590: ssi_with_retries - Does the server side include of a resource.
                   10591:                      if the ssi call returns an error we'll retry it up to
                   10592:                      the number of times requested by the caller.
1.596.2.12.2.  8(raebur 10593:4):                      If we still have a problem, no text is appended to the
1.531     jms      10594:                      output and we set some global variables.
                   10595:                      to indicate to the caller an SSI error occurred.  
                   10596:                      All of this is supposed to deal with the issues described
1.596.2.12.2.  8(raebur 10597:4):                      in LON-CAPA BZ 5631 see:

                   10601: Parameters:
                   10602:   resource   - The resource to include.  This is passed directly, without
                   10603:                interpretation to lonnet::ssi.
                   10604:   form       - The form hash parameters that guide the interpretation of the resource
                   10605:                
                   10606:   retries    - Number of retries allowed before giving up completely.
                   10607: Returns:
                   10608:   On success, returns the rendered resource identified by the resource parameter.
                   10609: Side Effects:
                   10610:   The following global variables can be set:
                   10611:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   10612:                               It is up to the caller to initialize this to false
                   10613:                               if desired.
                   10614:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   10615:                               of the resource that could not be rendered by the ssi
                   10616:                               call.
                   10617:    ssi_error_message   - The error string fetched from the ssi response
                   10618:                               in the event of an error.
