The following table lists the differences between the IIS version and the Windows Embedded Compact version of ISAPI filter functions.

ISAPI filter function

Windows Embedded Compact implementation

AddHeader

See ISAPI Filters and HTTP Headers.

AddResponseHeaders

Fully supported.

AllocMem

Fully supported.

GetHeader

See ISAPI Filters and HTTP Headers.

SetHeader

See ISAPI Filters and HTTP Headers.

WriteClient (ISAPI Filters)

IIS automatically breaks data that is larger than 16 KB into 16-KB chunks on requests from the WriteClient function. There is no support for chunked data in Windows Embedded Compact.

The web server ignores the members of the structure that the script can modify in the GetFilterVersion function.

SF_NOTIFY_SECURE_PORT must be set in pVer->dwFlags on return from GetFilterVersion if the filter wants to receive notifications for events that occur on connections that have been enhanced through SSL. Similarly, SF_NOTIFY_NONSECURE_PORT must be set in pVers->dwFlags if the filter wants to receive notifications for events that occur on non-secure connections.
