HTTP_RESPONSE_HEADERS structure (http.h)

The HTTP_RESPONSE_HEADERS structure contains the headers sent with an HTTP response.

Syntax

typedef struct _HTTP_RESPONSE_HEADERS {
  USHORT               UnknownHeaderCount;
  PHTTP_UNKNOWN_HEADER pUnknownHeaders;
  USHORT               TrailerCount;
  PHTTP_UNKNOWN_HEADER pTrailers;
  HTTP_KNOWN_HEADER    KnownHeaders[HttpHeaderResponseMaximum];
} HTTP_RESPONSE_HEADERS, *PHTTP_RESPONSE_HEADERS;

Members

UnknownHeaderCount

A number of unknown headers sent with the HTTP response and contained in the array pointed to by the pUnknownHeaders member. This number cannot exceed 9999.

pUnknownHeaders

A pointer to an array of HTTP_UNKNOWN_HEADER structures that contains one structure for each of the unknown headers sent in the HTTP response.

TrailerCount

This member is reserved and must be zero.

pTrailers

This member is reserved and must be NULL.

KnownHeaders[HttpHeaderResponseMaximum]

Fixed-size array of HTTP_KNOWN_HEADER structures. The HTTP_HEADER_ID enumeration provides a mapping from header types to array indexes. If a known header of a given type is included in the HTTP response, the array element at the index that corresponds to that type specifies the header value. Those elements of the array for which no corresponding headers are present contain a zero-valued RawValueLength member. Use RawValueLength to determine the end of the header string pointed to by pRawValue, rather than relying on the string to have a terminating null.
