Provides an interface to do server push operations, letting you rewrite
pages whose content changes regularly.
A server push operation automatically sends updates to a page on a
push-capable browser. CGI::Push exports the function
to implement page redraws. This method can be used on a CGI::Push
object or on its own:
$q = new CGI::Push; $q->do_push(-next_page => \&sub); # or do_push (-next_page => \&sub);
do_pushrequires one argument: a reference to a subroutine that will draw the next page. You may optionally specify a subroutine that draws the last page and the interval between page updates. Additional parameters to
do_pushare those that can be used with a CGI::headers object.
