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, audio/mpegurl, audio/x-mp3, audio/mpeg4, application/mpeg4-iod, 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).
