RFC

RFC 2183 Communicating Presentation Information in Internet Messages: The Content-Disposition Header Field
- RFC 2184 MIME Parameter Value and Encoded Word Extensions: Character Sets, Languages, and Continuations
- RFC 2231 MIME Parameter Value and Encoded Word Extensions: Character Sets, Languages, and Continuations

  In the extended BNF notation of [RFC 822], the Content-Disposition
  header field is defined as follows:

    disposition := "Content-Disposition" ":"
                   disposition-type
                   *(";" disposition-parm)

    disposition-type := "inline"
                      / "attachment"
                      / extension-token
                      ; values are not case-sensitive

    disposition-parm := filename-parm
                      / creation-date-parm
                      / modification-date-parm
                      / read-date-parm
                      / size-parm
                      / parameter

    filename-parm := "filename" "=" value

    creation-date-parm := "creation-date" "=" quoted-date-time

    modification-date-parm := "modification-date" "=" quoted-date-time

    read-date-parm := "read-date" "=" quoted-date-time

    size-parm := "size" "=" 1*DIGIT

    quoted-date-time := quoted-string
                     ; contents MUST be an RFC 822 `date-time'
                     ; numeric timezones (+HHMM or -HHMM) MUST be used

Test Cases for HTTP Content-Disposition header field (RFC 6266) and the Encodings defined in RFCs 2047, 2231 and 5987

Comme d'habitude, on constate que le puta.. de Internet Explorer de Windows nous emmerde ! (Toutes versions confondues de la 6 à 9).

Par exemple si votre fichier contient un point virgule (;), alors le nom du fichier est tronqué. attwithquotedsemicolon

Avec Android (2.2) et le navigateur par défaut WebKit 3.1 Mozilla/5.0 (Linux; U; Android 2.2; fr-fr; Desire_A8181 Build/FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1, les espaces posent problème : le fichier est renommée en ".bin", "-1.bin", "-2.bin" ...

Et les caractères hors ASCII sont supprimés : "toto%20esticietlà.txt" devient "toto20esticietl.txt"

Alors que depuis la version 4.0, aucun problème de la sorte.

Android and the HTTP download file headers
Android - An Open Handset Alliance Project : Issues Content-Disposition
- Issue 9991: Content-Disposition parsing does not understand special characters
- Issue 11422: Handling of Content-Disposition header does not conform to standard (filename in download)
Android browser/webview bug? Content-Disposition: attachment; filename=“xyz.txt”
Android HTTP header attachment filename ignored Android tablet will not accept spaces in the filename, the generic solution is remove spaces from the filename before sending the header
Avoiding content type issues when downloading a file via browser on Android 1. set the ContentType to application/octet-stream 2. put the Content-Disposition filename value in double uotes 3. write the Content-Disposition filename extension in UPPERCASE

Content-Disposition headers in .NET ASP.NET MVC 2 File method will manage the whole download for you, including generating the Content-Disposition header correctly for non-ASCII character filenames.
