Declaration

export external function set-request-header
   of                 value request     request
   to                 value  string     header

Argument definitions

request: The wsb.request OMX value containing the request header to be set.

header: The value of the header to be set.

Purpose

The wsb.set-request-header function sets the header value of the wsb.request object to the specified string value. This function is used to make sure that forwarded requests are sent to the right program for processing.

Example

This example shows how to reroute a SOAP request to a service called DoCalc. The program waits for the request, then fetches the request object's header and rewrites the SOAPAction header tupple to point to DoCalc. Then the program sets the request object's header using the wsb.set-request-header function to the new value. Then the program forwards the request using the function wsb.forward-request. Finally the function loops and waits for the next request for it to forward.
