prefer_head
-----------

   Type: integer
   Default: 0

   This variable affects ``expensive scoring'': If available, slrn uses
   the XOVER and XHDR extensions to retrieve only the needed header
   lines; otherwise, the HEAD NNTP command is used to get all headers.
   Although this notably increases network traffic, it might be faster,
   depending on your connection and the number of ``expensive'' headers
   you score on. In this case, you can set this variable and slrn will
   prefer HEAD over XOVER / XHDR.

   When set to 2, slrn never tries to use XOVER. This is only useful for
   servers with broken XOVER implementations.
