The APPSRV_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 APPSRV_HEADER, ODS is
not used and no HTTP header is written to _WEBOUT, a default
Content-type: text/html
header is generated.
To completely disable
Automatic Header Generation for a request, call the APPSRVSET DATA
step function, as follows:
data _NULL_;
rc = appsrvset("automatic headers", 0);
run;
