WINHTTP_MATCH_CONNECTION_GUID structure (winhttp.h)

  • Article

Represents the GUID of a connection, for purposes of connection-matching.

See the option flag WINHTTP_OPTION_MATCH_CONNECTION_GUID. That option takes as input a WINHTTP_MATCH_CONNECTION_GUID value.

Syntax

typedef struct _WINHTTP_MATCH_CONNECTION_GUID {
  GUID      ConnectionGuid;
  ULONGLONG ullFlags;
} WINHTTP_MATCH_CONNECTION_GUID, *PWINHTTP_MATCH_CONNECTION_GUID;

Members

ConnectionGuid

Type: GUID

A connection's GUID.

When WINHTTP_OPTION_MATCH_CONNECTION_GUID is set on a request, WinHttp attempts to serve the request on a connection matching ConnectionGuid.

ullFlags

Type: ULONGLONG

Flags.

Due to the nature of connection-matching logic, it's possible for an unmarked connection to be assigned to serve the request (if one is encountered before a matching marked connection is). Set ullFlags to WINHTTP_MATCH_CONNECTION_GUID_FLAG_REQUIRE_MARKED_CONNECTION if you don't want an unmarked connection to be matched. When using that flag, if no matching marked connection is found, then a new connection is created, and the request is sent on that connection.
