114: # ssi_with_retries - Does the server side include of a resource.
115: # if the ssi call returns an error we'll retry it up to
116: # the number of times requested by the caller.
117: # If we still have a proble, no text is appended to the

122: # http://bugs.lon-capa.org/show_bug.cgi?id=5631
123: # by informing the user that this happened.

125: # Parameters:
126: # resource - The resource to include. This is passed directly, without

128: # form - The form hash parameters that guide the interpretation of the resource
129: #
130: # retries - Number of retries allowed before giving up completely.
