Doh! you're absolutely right. It is the HTML headers that I need to modify. Thanks for the clarification :) I'm dealing with a few new technologies on this project.

Lots of reading material, thanks!

Ok, circling back around to this.

How do I modify the HTTP header before SOAP::Lite dispatches the request?

Frankly, I have no idea how to use XML::Compile, my grasp on SOAP::Lite is tenuous at best, so my attempts to replicate my working script with XML::Compile have been complete fail.

You said that you linked to an example where you were modifying the HTTP headers, but all I see is a hook that... calls the pp_twig sub. I'm not sure what it's doing, but as far as I can tell, it has nothing to do with the HTTP request headers. I'm pretty sure SOAP::Transport will be involved?

thanks for the guidance

EDIT: I think I need to be looking at LWP::UserAgent, not SOAP::Transport

Hmm, lets see,

$ perldoc LWP::UserAgent |grep -i hook

$

Ooops, the example didn't use hook, it used handler

$ perldoc LWP::UserAgent |grep -i handler
  Handlers
    Handlers are code that injected at various phases during the proce
+ssing
    handlers:
    $ua->add_handler( $phase => \&cb, %matchspec )

So maybe we're talking about something different?

$ua->default_header( $field => $value )

    This is just a short-cut for $ua->default_headers->header( $field 
+=> $value ). Example:

      $ua->default_header('Accept-Encoding' => scalar HTTP::Message::d
+ecodable());
      $ua->default_header('Accept-Language' => "no, en");

So couldn't I do something like:

$client->transport->default_header( 'my_special_header' => 'sha1hash')
+;

EDIT: hmm... this in the LWP doc confuses me,

request_preprepare => sub { my($request, $ua, $h) = @_; ... }

    The handler is called before the request_prepare and other standar
+d initialization of the request. This can be used to set up headers a
+nd attributes that the request_prepare handler depends on. Proxy init
+ialization should take place here; but in general don't register hand
+lers for this phase.

Is it saying in the request_prepare is where I should set my headers, or is this merely an option? I can't tell if $client->transport->default_headers() is working. haha. Was working on exporting a pcap (I develop on a vm but have wireshark locally)

Thanks for all the guidance. I can't tell if my frustration is coming through in my posts (which usually means it is) but it certainly isn't directed at you Anonymous Monk. I really do appreciate your helping me through all this.

EDIT: Hahaha!!!! IT does work, it helps to spell the name of the key right!

$client->transport->default_header( 'properly-speleeed-key' => $value 
+);

Does exactly what I want!!!
