The HSE_RESPONSE_VECTOR structure holds data about response elements used by the HSE_REQ_VECTOR_SEND support function.

If the HSE_IO_SEND_HEADERS flag is used, pszStatus and pszHeaders must not be NULL. If HSE_IO_SEND_HEADERS is not present, pszStatus and pszHeader must be NULL. Any other combination is invalid. |

The following response-related flags are valid:
Value | Meaning |
|---|
HSE_IO_ASYNC | Specifies asynchronous response. |
HSE_IO_CACHE_RESPONSE | This flag instructs IIS to populate the cache with the response elements defined in the HSE_RESPONSE_VECTOR. The cache population succeeds only if HSE_IO_FINAL_SEND is also set, and this HSE_RESPONSE_VECTOR constitutes the entire response for a given request. |
HSE_IO_DISCONNECT_AFTER_SEND | Specifies closing the connection after sending the response. |
HSE_IO_FINAL_SEND | Instructs IIS to not send any more response data after calling HSE_REQ_VECTOR_SEND with this flag set. |
HSE_IO_SEND_HEADERS | Specifies that headers and status are included with the response. |
HSE_IO_SYNC | Specifies synchronous response. |
- pszStatus
Specifies the status line to send on the response
- pszHeaders
A list of response headers.
- nElementCount
Number of HSE_VECTOR_ELEMENT elements that the lpElementArray points to.
- lpElementArray
A pointer to an array of HSE_VECTOR_ELEMENT structures.
IIS 6.0 requires the HSE_IO_FINAL_SEND flag with HSE_REQ_VECTOR_SEND for the response to be cached. This restriction does not apply to IIS 7.0.
