367516 - Message Header Extensions for Non-ASCII Text.

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[Maxim Butov]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1

I try to create http server with ability of file downloading. When I send the file content to client, I create a header into response like:

Content-Disposition:  attachment; filename="document.doc"

according to RFC 2183. FF works fine, it detects file name and prompts to save a file. The problem happens when I use locale-specific characters, which are not presented in US-ASCII encoding. Then I use Message Header Extensions (RFC 2047), and replace for example following string:

Content-Disposition:  attachment; filename="СМЕТЫ - Тест-план.xls"

to

Content-Disposition:  =?Cp1251?B?YXR0YWNobWVudDsgZmlsZW5hbWU9ItHMxdLbIC0g0uXx8i3v6+DtLnhscyI=?=

FF still suggests to save file but does not detect its filename.

Reproducible: Always



Expected Results:  
FF should properly process encoded HTTP headers.
