Release 10.1A: OpenEdge Development:

Using the SET-CALLBACK-PROCEDURE( ) method

This is the syntax for the SET-CALLBACK-PROCEDURE( ) method:

Syntax

SET-CALLBACK-PROCEDURE (callback-name, internal-procedure               [ , procedure-context ])

The parameters include:

callback-name — A character string value of "REQUEST-HEADER" or "RESPONSE-HEADER" to identify the type of callback. If this is the only parameter specified, no internal procedure will be executed for the specified callback (the default), and effectively clears any previous callback specification for this type of callback.
internal-procedure — A character string value containing the name of the internal procedure you want executed for the specified callback or an empty string, which deletes a previous callback definition.
procedure-context — (Optional) A procedure object handle that points to an active procedure context that contains the specified internal procedure. This is typically a persistent procedure instantiated in the current OpenEdge session or the method calling context (THIS-PROCEDURE). If not specified, it is the value of THIS-PROCEDURE.
