Subject [users@httpd] How do I follow the XHTML Content-Type recommendations?
Date Fri, 17 Jul 2009 17:41:20 GMT
If a client requests an XHTML file, it says to do normal
content-negotiation.  If the client's HTTP Accept header says they like
text/html more, send them that.  If it says they like application/xhtml+xml
more, send them that.

Fine.  I have even done that successfully with two different files.

Except I can't figure out how to provide multiple Content-Types for a
single file.  And I don't think creating multiple copies of the document
(even with linkes) is an appropriate solution.

   AddType "application/xhtml+xml,text/html; qs=0.01" .html

Tells the client "Content-Type: cation/xhtml+xml,text/html; qs=0.01",
which is no good.

An apache type-map always returns the Content-Type specified by AddType in
my main apache config file.


Test cases:

Both of these files are the same, hard linked to each other.

http://www.chaosreigns.com/xhtmltest/addtype.xhtml

Apache config:

   AddType "application/xhtml+xml,text/html; qs=0.01" .xhtml

The test: 

   $ telnet www.chaosreigns.com 80
   Trying 64.71.152.40...
   Connected to panic.chaosreigns.com.
   Escape character is '^]'.

   Content-Type: text/html

When I have "AddType "application/xhtml+xml" .html" in my main apache
config and specify Content-Type: text/html, I get application/xhtml+xml.
This is its current state.

I think I should file bugs for these?



It also suggests that if neither text/html or application/xhtml+xml are
listed in the Accept header, that application/xhtml+html should not be
used.  I suppose it would be nice to be able to do that for particularly
bad browsers.
