Details

The STPSRV_HEADER function enables automatic header generation. You can add a header to the default list or modify an existing header from the list. When you modify the value of an existing header, the old value becomes the return value of the function.

The automatic HTTP header generation feature recognizes Output Delivery System (ODS) output types and generates appropriate default content-type headers. If no content type is specified with STPSRV_HEADER, then ODS is not used and no HTTP header is written to _WEBOUT. A default

Content-type:
                     text/html

header is generated. For a list of commonly used HTTP headers, see Using HTTP Headers.

Note: The APPSRV_HEADER function can be used instead of STPSRV_HEADER. This feature is provided in order to enable you to convert existing SAS/IntrNet programs to stored processes.
