Moreover, the Content-Type used for json was not the best choice. It was

application/jsonrequest.

As specified in RFC4627, it should be application/json.

The status page does not return a valid Content-Type header:

...
text/plain
Content-type: text/plain
...

it should be

...
Content-type: text/plain
...

It affects apache but also any other front web servers. Nginx is more
tolerant 
and ignores unknown / malformed headers but text/html was use instead.

Description:
------------
Apache 2 ends up with an error while trying to get content of /status
url. Ping url works fine.
Same problem with /status?json and /status?html.

Apache version: 2.2.16, mpm-worker
mod_fastcgi version: 2.4.6

Test script:
---------------
<IfModule mod_fastcgi.c>
	FastCGIExternalServer /php5-fpm-handler -socket
"/var/run/php5-fpm.sock"
	AddHandler php5-fcgi .php

	<LocationMatch "/(ping|status)">
		SetHandler php5-fcgi-virt
		Action php5-fcgi-virt /php5-fpm-handler.fcgi virtual
	</LocationMatch>

	Action php5-fcgi /php5-fpm-handler.fcgi
	ScriptAlias /php5-fpm-handler.fcgi /php5-fpm-handler
</IfModule>

Expected result:
----------------
FPM status page

Actual result:
--------------
500 Internal error

Logged in Apache's error log:
[Mon Aug 23 04:16:55 2010] [error] [client 127.0.0.1] FastCGI: comm with
server "/php5-fpm-handler" aborted: error parsing headers: malformed
header 'text/plain'
