2024-02-22

The HttpCreateServerSession function creates a server session for the specified version.

Syntax

HTTPAPI_LINKAGE ULONG HttpCreateServerSession(
  [in]  HTTPAPI_VERSION         Version,
  [out] PHTTP_SERVER_SESSION_ID ServerSessionId,
  [in]  ULONG                   Reserved
);

Parameters

[in] Version

An HTTPAPI_VERSION structure that indicates the version of the server session. For version 2.0, declare an instance of the structure and set it to the predefined value HTTPAPI_VERSION_2 before passing it to HttpCreateServerSession.

The version must be 2.0; HttpCreateServerSession does not support version 1.0 request queues.

[out] ServerSessionId

A pointer to the variable that receives the ID of the server session.

[in] Reserved

Reserved. Must be zero.

Return value

If the function succeeds, it returns NO_ERROR.

If the function fails, it returns one of the following error codes.

Value	Meaning
ERROR_REVISION_MISMATCH	The version passed is invalid or unsupported.
ERROR_INVALID_PARAMETER	The pServerSessionId parameter is null or the Reserved is non zero.

Remarks

Server sessions own a set of URL Groups. They are top-level configuration containers for configuration information that applies to all of the URL Groups created under them. For more information about configuring a server session, see HttpSetServerSessionProperty.

The HTTP Server API does not support asynchronous I/O for server sessions.

When the server session is no longer required, or before the application terminates, application must delete the server session by calling HttpCloseServerSession. When a server session is deleted all of the associated URL Groups are also automatically deleted.
