Summary: "AddType application/x-type-map" Still in Use (Not
backwards-compatibility)
Product: Apache httpd-2
Version: 2.2.4
Platform: All
URL: http://httpd.apache.org/docs/2.2/content-
negotiation.html#type-map
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Documentation
AssignedTo: bugs@httpd.apache.org
ReportedBy: imacat@mail.imacat.idv.tw
Dear all,
Hi. This is imacat from Taiwan. In the Apache 2.2 documentation:
http://httpd.apache.org/docs/2.2/content-negotiation.html#type-map
"A type map is a document which is associated with the handler named
type-map (or, for backwards-compatibility with older Apache configurations, the
MIME-type application/x-type-map)."
I tried and get really confused with this for several days of working.
After digging into mod_negotiation.c it turned out that the MIME-type
"application/x-type-map" is still in use. It is NOT only for
backwards-compatibility, as static. If you create a type map page.html.var for
the URL page.html and expect it to work, as the example on the documentation
says, you have to:
1. Turn on MultiViews.
2. Add this line: "AddType application/x-type-map .var".
This is contrary to what the documentation says. As a result, the example
won't work if you follow the documentation.
I think this should be corrected.

Well, I believe you did not read my report carefully. It does not work IN
CERTAIN CONDITION. To be specific, in the example stated in the documentation.
I have created a simple test case and attached a console log so that you can
examing it. It is excactly the example in the documentation, not a single word
changed.
Please tell me if you need any more information. And, PLEASE, do not close
a bug so quickly.

Yes, I'm not supposed to do so. I don't know that I have to do so in order
to get the documented example working after several days of trying.
Please understand that I classify this as a "bug in the documentation".
Since I have looked into the code, I do understand its logic.
The last sentence in the second paragraph under the heading "Using a
type-map file" says:
http://issues.apache.org/bugzilla/show_bug.cgi?id=41885#add_comment
"This file would be named foo.var, as it describes a resource named foo."
In an earlier paragraph "About Content Negotiation", the first sentence of
the last paragraph:
http://httpd.apache.org/docs/2.2/content-negotiation.html#about
"A resource is a conceptual entity identified by a URI (RFC 2396)."
As for "a resource named foo", what's wrong if I request for foo? Am I
supposed to request "foo.var" for "a resource named foo"?
Also, the second paragraph under "Using a type-map file":
"It is conventional to begin a map file with an entry for the combined
entity as a whole (although this is not required, and if present will be ignored)."
I suppose this means the first line "URI: foo" in the example. So I request
the "combined entity", the "foo". What's wrong with this anyway? If there is
no such combined entity "foo", why does it say so? If foo.var is describing a
resource named foo.var, shouldn't it be documented this way?

> AddHandler type-map .var
> then you need to request the file including the .var extension. Check
> conf/extra/httpd-manual.conf to see how it is done (where .html is designated as

Actually, it is the first thing I checked, even before I read the
documentation, in order to get our local documentation copy working.

Please fix this in the documentation. I would not like to see another one
wasting so much time on this.

AddHandler type-map
certainly does work. We use it on apache.org.
There must be something else going on in your config.

------- Additional Comments From slive@apache.org 2007-03-19 19:44 -------
Type-maps do indeed work as documented. You are *not* supposed to be combining
type-maps with MultiViews -- they are alternatives (they docs say "This is done
in one of two ways", not "use both of these").
If you have
AddHandler type-map .var
then you need to request the file including the .var extension. Check
conf/extra/httpd-manual.conf to see how it is done (where .html is designated as
being a type-map).
When you try to combine MultiViews and type-maps, things get really confusing. I
wouldn't recommend it at all, and the fact that you got it to work using a
backward-compat feature is probably accidental.
But it seems there is some code trying to handle that case, so I'll leave this
bug report open in case anyone is interested in trying to make it work more
predictably.
