Use the http.setResponseHeader() function to set the value of a response header. You can use this function in both request and response rules:
# Mask the 'Server' response header
http.setResponseHeader( "Server", "Unknown web server" );
# Work round browser/proxy bugs and prevent caching
http.setResponseHeader( "Pragma", "no-cache" );
http.setResponseHeader( "Cache-Control", "no-cache" );
http.setResponseHeader( "Expires", "0" );
You can also delete a response header with the http.removeResponseHeader() function.
