IBM AS/400E manual Name Translation

This function allows user verification of the security tokens. This step is performed based on the authentication scheme.

Only HTTP_extract() and HTTPD_set() are valid during this step.

Name Translation

void

HTTPD_LINKAGE NameTrans(

unsigned char *handle, long *return_code);

This function provides a mechanism for mapping URLs to objects.

Only HTTPD_extract() and HTTPD_set() are valid during this step.

Authorization

void

HTTPD_LINKAGE Authorization(

unsigned char *handle, long *return_code);

This function verifies that the identified object may be returned to the client. If you are doing basic authentication, you must generate the required WWW-Authentication headers.

Only HTTPD_extract() and HTTPD_set() are valid functions during this step.

Object Type

void

HTTPD_LINKAGE ObjType(

unsigned char *handle, long *return_code);

This step checks to see if the object exists and performs object typing.

Only HTTPD_extract() and HTTPD_set() are valid during this step.

Service

void

HTTPD_LINKAGE Service(

unsigned char *handle, long *return_code);

This function satisfies the request, if not satisfied in the PreExit.

All server-predefined functions are valid during this step. Refer to the Enable directive in the HTTP Server for AS/400 Webmaster’s Guide, GC41-5434 for information.

Data Filter

Filters data as a stream class, which means that each of its functions acts like a segment of pipe down which data flows. For this step, you must use three application functions:

void

HTTPD_LINKAGE open(

unsigned char *handle, long *return_code);

This function performs any initialization (such as buffer allocation) that is required to process the data for this stream. An error return code causes this filter to abort.
