use strict;
use LWP;
use LWP::ConnCache;
use LWP::Debug qw(+);
LWP::Debug::level('+');
&main();
sub main {
my $browser = new LWP::UserAgent;
my $cache = $browser->conn_cache(LWP::ConnCache->new( ));
$browser->conn_cache->total_capacity(undef);
my $url = "http://172.26.65.1/Vupload";
my $request = new HTTP::Request( GET => $url );
my $headers = $request->headers();
$headers->header( 'Accept-Encoding','gzip, deflate');
my $response = $browser->request($request);
if ($response->is_success) {
print $response->decoded_content;
}
else {
die $response->status_line;
}
} |
J'obtiens systematiquement la reponse ci-apres:

J'utilise wiresharc pour voir la difference entre mon script et un browser du commerce (Mozilla ou IE)
Voila la seule difference que je vois dans la requete:
TE: deflate,gzip;q=0.3
et
Connection: Keep-Alive, TE
au lieu de
Connection: Keep-Alive
Qui peut me dire si je suis sur la bonne piste et comment enlever ce TE.
Je suppose que le client ne supporte pas le transfert-encoding.
Merci
