                   10315:

                   10320: 
                   10321: Do an ssi with retries:
                   10322: While I'd love to factor out this with the vesrion in lonprintout,
                   10323: 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
                   10324: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   10325: 
                   10326: At least the logic that drives this has been pulled out into loncommon.
                   10327: 
                   10328: 
                   10329: 
                   10330: ssi_with_retries - Does the server side include of a resource.
                   10331:                      if the ssi call returns an error we'll retry it up to
                   10332:                      the number of times requested by the caller.
                   10333:                      If we still have a proble, no text is appended to the
                   10334:                      output and we set some global variables.
                   10335:                      to indicate to the caller an SSI error occurred.  
                   10336:                      All of this is supposed to deal with the issues described
                   10337:                      in LonCAPA BZ 5631 see:

                   10341: Parameters:
                   10342:   resource   - The resource to include.  This is passed directly, without
                   10343:                interpretation to lonnet::ssi.
                   10344:   form       - The form hash parameters that guide the interpretation of the resource
                   10345:                
                   10346:   retries    - Number of retries allowed before giving up completely.
                   10347: Returns:
                   10348:   On success, returns the rendered resource identified by the resource parameter.
                   10349: Side Effects:
                   10350:   The following global variables can be set:
                   10351:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   10352:                               It is up to the caller to initialize this to false
                   10353:                               if desired.
                   10354:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   10355:                               of the resource that could not be rendered by the ssi
                   10356:                               call.
                   10357:    ssi_error_message   - The error string fetched from the ssi response
                   10358:                               in the event of an error.
