libcURL.ResponseHeaderEngine.HasHeader

Method Signature

 Function HasHeader(Name As String, Origin As libcURL.HeaderOriginType = libcURL.HeaderOriginType.Any, RequestIndex As Integer = -1) As Boolean

Parameters

Name	Type	Comment
Name	String	The name of the headers to look for.
Origin	HeaderOriginType	Optional. The origin type of the headers to look for.
RequestIndex	Integer	Optional. The request index of the headers to look for.

Remarks

Returns True if at least one header exists which matches all of the parameters. If a parameter is unspecified then all headers match it.

Response headers may originate from several different stages in an HTTP(S) operation depending on circumstances such as proxying, HTTP version, redirection, etc. The Origin parameter restricts the query to headers originating only during a particular stage.

A single transfer might consist of a series of HTTP requests, for example redirects or multi-stage authentication. The RequestIndex parameter lets you specify which request you want. 0 being the first request, 1 being the next, and so on. -1 refers to the most recent request in the series. -2 refers to all headers across all transfers. -2 refers to all headers across all requests. Refer to the RequestCount() method to determine the number of transfers.
