Detailed Description

Client is a common base for classes such as HttpStateData and FtpStateData. All such classes must be able to consume request bodies from a BodyPipe or ICAP producer, adapt virgin responses using ICAP, and provide a consumer with responses.

◆ Start()

void AsyncJob::Start ( const Pointer & job )

staticinherited

Promises to start the configured job (eventually). The job is deemed to be running asynchronously beyond this point, so the caller should only access the job object via AsyncCalls rather than directly.

swanSong() is only called for jobs for which this method has returned successfully (i.e. without throwing).
