The number of requests each redirector helper can handle in parallel. Defaults to 0 which indicates the redirector is a old-style single threaded redirector. When this directive is set to a value >= 1 then the protocol used to communicate with the helper is modified to include a request ID in front of the request/response. The request ID from the request must be echoed back with the response to that request.  |
