◆ Data()

bool XrdHttpReq::Data ( XrdXrootd::Bridge::Context & info,
const struct iovec * iovP,
int iovN,
int iovL,
bool final )
virtual

Effect a client data response.

The Data() method is called when Run() resulted in a successful data response. The method should rewrite the data and send it to the client using the associated XrdLink object. As an example, 1) Result::Data(info, iovP, iovN, iovL) is called. 2) Inspect iovP, rewrite the data. 3) Send the response: info->linkP->Send(new_iovP, new_iovN, new_iovL); 4) Handle send errors and cleanup(e.g. deallocate storage). 5) Return, the exchange is now complete.

Parameters
infothe context associated with the result.
iovPa pointer to the iovec structure containing the xrootd data response about to be sent to the client. The request header is not included in the iovec structure. The elements of this structure must not be modified by the method.
iovNthe number of elements in the iovec structure array.
iovLtotal number of data bytes that would be sent to the client. This is simply the sum of all the lengths in the iovec.
finalTrue is this is the final result. Otherwise, this is a partial result (i.e. kXR_oksofar) and more data will result causing additional callbacks.
Returns
true continue normal processing. false terminate the bridge and close the link.
Parameters
infothe result context
iovPpointer to data array
iovNarray count
iovLbyte count
finaltrue -> final result

Effect a client acknowledgement.

The Done() method is called when Run() resulted in success and there is no associated data for the client (equivalent to a simple kXR_ok response).

Parameters
infothe context associated with the result.
Returns
true continue normal processing. false terminate the bridge and close the link.

◆ Error()

bool XrdHttpReq::Error ( XrdXrootd::Bridge::Context & info,
int ecode,
const char * etext )
virtual

Effect a client error response.

The Error() method is called when an error was encountered while processing the Run() request. The error should be reflected to the client.

Parameters
infothe context associated with the result.
ecodethe "kXR" error code describing the nature of the error. The code is in host byte format.
etexta null terminated string describing the error in human terms
Returns
true continue normal processing. false terminate the bridge and close the link.
Parameters

◆ File()

int XrdHttpReq::File ( XrdXrootd::Bridge::Context & info,
int dlen )
virtual

Notify callback that a sendfile() request is pending.

The File() method is called when Run() resulted in a sendfile response (i.e. sendfile() would have been used to send data to the client). This allows the callback to reframe the sendfile() data using the Send() method in the passed context object (see class Context above).

Parameters
infothe context associated with the result.

Returns
true continue normal processing. false terminate the bridge and close the link.

◆ Redir()

bool XrdHttpReq::Redir ( XrdXrootd::Bridge::Context & info,
int port,
const char * hname )
virtual

Redirect the client to another host:port.

The Redir() method is called when the client must be redirected to another host.

Parameters
infothe context associated with the result.
portthe port number in host byte format.
hnamethe DNS name of the host or IP address is IPV4 or IPV6 format (i.e. "n.n.n.n" or "[ipv6_addr]").
Returns
true continue normal processing. false terminate the bridge and close the link.
Parameters
infothe result context
portthe port number
hnamethe destination host

Implements XrdXrootd::Bridge::Result.
