Apache（2.0）mod_headers是否不输出环境变量？

Question

My .htaccess file:

Header add X-Hello "time %D"

Now I check to see what it looks like, check out the X-Hello header:

$curl -v http://foo.com/bar.php
...
< HTTP/1.1 200 OK
< Date: Wed, 06 Oct 2010 20:43:39 GMT
< Server: Apache
< Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
< Expires: Thu, 19 Nov 1981 08:52:00 GMT
< Pragma: no-cache
< Set-Cookie: PHPSESSID=7d32d8fch8qrnnuvoqqopr74c0; path=/
< X-Hello: time %D
< Transfer-Encoding: chunked
< Content-Type: text/html

Which is clearly contrary to the Apache documentation below. Is there some other directive that mod_headers needs in order to interpolate environment variables?

Answer 1

除非另有说明，否则托管提供程序承认仍使用Apache 1.3，该版本未对mod_header值进行mod_header 。
