Hi,

I am try to configure a modem that has a http-api.

When I capture what the browser-based GUI does I can see that it sends http-headers that look like this: 

__RequestVerificationToken: acP92nszWSeNIAeL/Al9Rj24scVQXt+o

[download]
This is what I try to replicate in a perl-script.

What I do is this: 

my $mech = WWW::Mechanize->new;
my $r = HTTP::Request->new("POST", $some_url);
$r->header("__RequestVerificationToken" => $key);
# set content and some other headers here
$mech->request($r);

[download]
But when I capture what the script sends I find that the leading underscores seem to get replaced with minuses, i.e. 
--RequestVerificationToken: whatever

[download]
So my question is: Why is that and how can I turn it off so I can send headers with leading double-underscores?

Many thanks!
