68420 - W3C CUAP: Save resources using system naming conventions

Status: RESOLVED FIXED

(Core Graveyard :: File Handling, defect)

Description

[Gervase Markham [:gerv]]

[ This bug is one of the recommendations in the W3C's "Common User Agent 
Problems" document, URL above. One bug has been filed on each recommendation, 
for deciding whether we do it and, if not, whether we should. ]

3.1 Save resources retrieved from the Web on the local system using the
appropriate system naming conventions.

     The media type of a resource retrieved by HTTP [RFC2616] is determined
     by the content type and encoding returned by the server in the
     response headers.

     If the user wants to save a resource locally, the user agent should
     respect the system naming conventions for files (e.g. PNG images
     usually have a .png extension).

     Example:

     http://www.w3.org/TR/1999/REC-html401-19991224/html40.ps is a view of
     the gzip'ed PostScript version of the HTML 4.01 specification. The
     HTTP headers sent by the server include:

     Content-Type: application/postscript; qs=0.001
     Content-Encoding: gzip

     If saved locally, the filename on most computers should be
     html40.ps.gz for the applications to recognize the file type.

     Wrong: Saving this compressed PostScript document as html40.ps is
     likely to confuse other applications.

This does not apply on Mac OS and (I think) BeOS.

[Andreas M. "Clarence" Schneider]

Depends on
- bug 31519 "Save as: should add extension to match content type"
- bug 24817 "No filenames generated for index files on d/l"
- bug 35956 "File extension not changed but gzipped files expanded when saving"
- bug 51852 "File -> Save Page As... doesn't honor Content-encoding when page 
has no-cache"
