 Hi Marc,
 
 first the good message: it fixes a little bit:
 
 No Accept: -> browser gets the default 
 Accept: de    browser gets german
 Accept: de,en,*  browser gets german if possible or en, or ...
 Accept: de,*  browser gets englisch hu? schould not be, what?
 
 Current Configuration: 
 
 LanguagePriority de en fr 
 
 but now we can live with it.
 
 But the mod_negotiation seems to have another problem:
 
 the vary-maps dont work at all, I ve set up a test with
 a file picture.gif (62079 bytes) and a file picture.jpg (22578 bytes)
 
 now one of the tests:
 HEAD /other/picture.var HTTP/1.0
 Accept: image/gif;q=0.5;maxbytes=30000, image/jpeg;q=0.4, */*
 
 HTTP/1.1 200 OK
 Date: Mon, 24 Feb 1997 04:42:01 GMT
 Server: Apache/1.2b7
 Connection: close
 Content-Type: image/gif
 Expires: Mon, 24 Feb 1997 04:42:01 GMT
 Last-Modified: Sat, 11 Jan 1997 16:49:31 GMT
 ETag: "9864-f27f-32d7c49b"
 Content-Length: 62079
 Accept-Ranges: bytes
 
 
 but I expected the picture.jpg here, because the file as .gif
 is 62079 bytes and therefore larger than maxbytes.
 
 
 have you tried this?
 
 regards,

If you are chatting with this person, remind them that if they use a
var-map file then _NO_ information is read from the file system -- in
particular, if they want file sizes to be taking into consideration, they
must add them manually to the var-map (as "Content-Length: 62079" etc).

If they do have this information in their map file, then it might be a
bug. 

By the way, this can cause confusion because the file information is used
when the variant is directly requested. For example, the type-map could
say

  URI: fish.en.html
  Content-Language: de

and it would be negotiated on as a German document, but when actually
requested it would be marked as being in English. 

It might also be worth noting that maxbytes is not part of HTTP/1.1 so new
browsers probably won't bother sending it (I'm not aware of any existing
ones which sent it either).
