Abusing this ini parameter to send multiple headers is not something that should be included as an example in the manual. There are better ways to do it.

-    Custom headers may be sent using <link linkend="context.http">context

-    Custom headers may be sent with an HTTP request 
-    by taking advantage of a side-effect in the
-    handling of the <literal>user_agent</literal> INI setting.
-    Set <literal>user_agent</literal> to any valid string
-    (such as the default <literal>PHP/version</literal> setting)
-    followed by a carriage-return/line-feed pair and any
-    additional headers.
