The child URL, in Unicode, to be invoked. If pszUrl is NULL or the child URL's URI-stem, excluding the query string, matches the parent's, the same request will be re-processed. Reprocessing of this ISAPI depends upon the absence of HSE_EXEC_URL_IGNORE_CURRENT_INTERCEPTOR, explained below.
The new HTTP method seen by the child URL for processing. If pszMethod is NULL, this specifies that no change to the HTTP method is made and the child thereby sees the parent's HTTP method.
Pointer to the sequence of request headers seen by the child URL for processing. This member completely replaces the headers seen by the child. To pass along the parent's headers without change, set this parameter to NULL.
A pointer to HSE_EXEC_URL_USER_INFO, a structure that specifies custom authentication information for the child URL processing. If this pointer is NULL, the child URL inherits the authentication information from the parent.
A pointer to HSE_EXEC_URL_ENTITY_INFO, a structure that specifies entity body modifications for the child URL processing. If this pointer is NULL, the child URL has access to any outstanding and unconsumed entity body.
Flags that control how the child request is processed.
This flag suppresses any non-stream response headers sent by the child. For example, WriteClient of data representing response headers is impossible to suppress, but structured headers sent using HSE_REQ_SEND_RESPONSE_HEADER, HSE_REQ_VECTOR_SEND, and HSE_REQ_SEND_CUSTOM_ERROR are suppressed. Absence of this flag allows the child's response headers to be a part of the response.
When a parent ISAPI, acting as a Wildcard Scriptmap Mapping sets this flag, it prevents the execution of the parent ISAPI for the remaining duration of the child request. In particular, if recursion of the child request occurs or the same parent ISAPI is otherwise triggered as a scriptmap from another virtual directory, setting this flag prevents the parent ISAPI from processing the request again.
When this flag is present and pszChildHeaders is NULL, the following headers will be removed from the child URL's processing if they exist:
If pszChildHeaders is not NULL, this flag has no effect.
When this flag is present, any entity body sent out as a part of a custom error will be suppressed. The headers of the custom error may be further suppressed with HSE_EXEC_URL_NO_HEADERS to allow the parent complete control of the response.
