Re: conseil téléchargement

Salut,

Le Trucs simple est de mettre ton fichier PDF dans un ZIP, idéalement avec autoextraction. Ou encore enlever l'association dans les navigateur local des extension PDF, il forcera alors le téléchargement puisque qu'il ne reconnaît plus le format...

Mais si tu peux utiliser des langages serveur comme la ASP, tu peux forcer un téléchargement.

En ASP
Response.AddHeader "content-disposition","attachment; filename=fname.ext"

Voici un très bon code pour le faire en ASP

Response.Charset = "UTF-8"
Response.ContentType = ContentType

Response.BinaryWrite objStream.Read
Response.Flush

objStream.Close

En PHP c'est

<?
header("Content-type: application/pdf");
header("Content-Disposition: attachment; filename=downloaded.pdf");
...
?>
