                   10900: =head1 OVERVIEW
                   10901: 
                   10902: Do an ssi with retries:
                   10903: While I'd love to factor out this with the vesrion in lonprintout,
                   10904: 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
                   10905: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   10906: 
                   10907: At least the logic that drives this has been pulled out into loncommon.
                   10908: 
                   10909: 
                   10910: 
                   10911: ssi_with_retries - Does the server side include of a resource.
                   10912:                      if the ssi call returns an error we'll retry it up to
                   10913:                      the number of times requested by the caller.
1.596.2.12.2.  8(raebur 10914:4):                      If we still have a problem, no text is appended to the
1.531     jms      10915:                      output and we set some global variables.
                   10916:                      to indicate to the caller an SSI error occurred.  
                   10917:                      All of this is supposed to deal with the issues described
1.596.2.12.2.  8(raebur 10918:4):                      in LON-CAPA BZ 5631 see:

                   10921: 
                   10922: Parameters:
                   10923:   resource   - The resource to include.  This is passed directly, without
                   10924:                interpretation to lonnet::ssi.
                   10925:   form       - The form hash parameters that guide the interpretation of the resource
                   10926:                
                   10927:   retries    - Number of retries allowed before giving up completely.
                   10928: Returns:
                   10929:   On success, returns the rendered resource identified by the resource parameter.
                   10930: Side Effects:
                   10931:   The following global variables can be set:
                   10932:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   10933:                               It is up to the caller to initialize this to false
                   10934:                               if desired.
                   10935:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   10936:                               of the resource that could not be rendered by the ssi
                   10937:                               call.
                   10938:    ssi_error_message   - The error string fetched from the ssi response
                   10939:                               in the event of an error.
