2.2.1.4.16 pipeline-request

  • Article

This token is used by the client to identify the current request as a pipeline request (section 2.2.2.5). When attempting to determine if the pipelined mode of operation can be used, the client will send two pipeline requests and the pipeline request token MUST be present in both of those requests. The two requests MUST be sent "back-to-back", that is, be pipelined, as specified in [RFC2616] section 8.1.2.2.

This token MUST have a value of 1.

This token is defined for use only in requests sent to a server using the HTTP 1.1 protocol.<30>

The syntax of the pipeline-request token is defined as follows.

 pipeline-request   = "pipeline-request=1"

Example:

 Pragma: pipeline-request=1
