 Does anyone have success/failure stories using Push responses?
 
 Please share.  Thanks.

I have successfully developed a couple of interesting 
push-based solutions, but the fact that IE didn't (doesn't?) 
support push meant that they weren't useful to my user base.

RE: mod_perl caching form data?

This is most likely a variable scoping problem as described here:

  http://perl.apache.org/docs/1.0/guide/frequent.html

As a rule of thumb, variables which are 'local' to a subroutine
should be declared with 'my' and variables which should be
visible to all routines in a file should be declared with 'our'.

eg:

  use CGI;

  our $cgi = new CGI;

  ...

  sub do_something {
my($arg1, $arg2) = @_;
...
  } 

If your script has global variables which are declared with 'my',
they will cause problems.
