* 6.15. Also-Control (制御もする。)

[PRE[
          The Also-Control header content marks the article as being a
          control  message IN ADDITION to being a normal news article,
          and specifies the desired actions:

[PRE[
               Also-Control-content = Control-content
]PRE]

[PRE[
          An article with an Also-Control header is filed  and  passed
          on  normally,  but the content of the Also-Control header is
          processed as if it were found in a Control header.
]PRE]

[PRE[
               NOTE: It is sometimes desirable to piggyback  con-
               trol  actions  on  a  normal  article, so that the
               article will be filed normally but  will  also  be
               acted  on  as  a  control message.  This header is
               essentially a generalization of Supersedes.
]PRE]

NOTE: Be warned that  some  old  relayers  do  not implement Also-Control.

参考: 古い中継者は Also-Control を実装していないことに注意せよ。

An  article with an Also-Control header MUST not have a Control or 
Supersedes header.

Also-Control 頭のついた記事は Control 頭や Supersedes 頭も
つけては''いけません''。
