Hi,
Using this (but it's not exactly what I want) it works

test-1.tex %%%%%%%%%%%%%%

\setuppagenumbering
  [alternative=doublesided,location=]

\definelayout
  [1]
  [header=10mm]

\setuplayout
  [header=0pt,
   height=middle]

\setupbackgrounds
   [header]
   [text]
   [frame=off,bottomframe=on,
     framecolor=lightgray,rulethickness=1pt]


\starttext
\dorecurse{5}{\samplefile{lorem}}
%\dorecurse{1}{\samplefile{lorem}}
\stoptext

%%%%%%%%%%%%%%%%%%ù

Using this (almost what I'm trying to do) without success

test-2.tex %%%%%%%%%%%%%
\setuppagenumbering
  [alternative=doublesided,location=]

\setupbackgrounds
  [header]
  [text]
  [frame=off,bottomframe=on,
   framecolor=lightgray,rulethickness=1pt]

\startsetups[header]
  \doifelse{\totalnumberofpages}{1}
    {\setupheadertexts[\setups{header}]}
    {}
\stopsetups


\starttext
\dorecurse{5}{\samplefile{lorem}}
%\dorecurse{1}{\samplefile[lorem]r}
\stoptext

%%%%%%%%%%%%%%%%%%%
