Package: elinks
Version: 0.11.1-1
Severity: normal
Tags: upstream
Hello,
Elinks sends wrong Accept: header to http servers and breaks content
negotiation. For example: I have file named a.xml with source of some
webpage and a.xhtml with result (created with xsltproc or xalan). When
I request http://server/a (without extension), elinks sends
Accept: */*. Webserver send smaller file (probably a.xml), which elinks
can't understand, since elinks doesn't speak xml.
How does it work for other browsers?
====================================
First Opera 8, which also doesn't support xml:
#v+
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; X11; Linux i686; en) Opera 8.54
Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png,
image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1
Accept-Language: en
Accept-Charset: iso-8859-1, utf-8, utf-16, *;q=0.1
Accept-Encoding: deflate, gzip, x-gzip, identity, *;q=0
#v-
It prefers text/html and application/xhtml+xml over application/xml and
*/*.
Elinks sends:
#v+
User-Agent: ELinks/0.11.1 (textmode; Linux 2.6.16-ck11 i686; 128x48)
Accept: */*
Accept-Encoding: gzip
Accept-Language: pl
#v-
With obviously wrong Accept: (since it doesn't support every format
equally).
Lynx (also not supporting xml):
#v+
Accept: text/html, text/plain, application/x-java-jnlp-file,
application/x-bittorrent, application/x-troff-man, audio/mpeg, video/x-msvideo,
video/mpeg, video/quicktime, video/x-ms-asf, video/x-ms-wmv, application/x-tar,
application/x-gtar
Accept: application/ogg, application/x-msdos-program, image/*, video/x-mpeg,
video/mpeg-system, video/x-mpeg-system, audio/x-wav, video/mpeg4,

application/mpeg4-muxcodetable
Accept: application/x-ogg, application/x-ms-asf-plugin, application/x-mplayer2,
application/wordperfect5.1, application/x-applix-word,
application/x-palm-database, text/*, application/x-debian-package, audio/basic,
*/*;q=0.01
Accept-Encoding: gzip, compress
Accept-Language: po,en
User-Agent: Lynx/2.8.5rel.1 libwww-FM/2.14 SSL-MM/1.4.1 GNUTLS/1.0.16
#v-
It lists text/html explictly and lowers priority of */*. (It sends
wrong Language, but it's another bug ;-)
Even MS IE works correctly (by supporting xml ;-)
Other browsers headers in attachment.
How fix it?
===========
It will be rather easy, because wrong header is hardcoded in source:
file src/protocol/http/http.c, line 715.
You may set it to something like:
Accept: text/html, application/xhtml+xml;q=0.9, text/plain;q=0.8, text/*;q=0.7,
*/*;q=0.1
The */* part is needed, because we want to download and save on disc
other types.
Not attaching patch, because I'm not sure if it's correct (but I think
so ;-) and because You (or Upstream) may prefer other Accept (but
please change it, the current one is wrong).
Thanks,
