Many thanks for your reply, Aditya.

Your approach is really interesting, but I don’t know how to mix it with
the first run mode.

  \startmode[*first]
  \startluacode
  io.write("\n\n Document URL?    ")
  document.url_address = io.read()
  \stopluacode

  \definedataset[document_data]
  \setdataset[document_data]
      [url=\cldcontext{document.url_address}]
  \stopmode

  \starttext
  \startTEXpage[offset=1em]
  \datasetvariable{document_data}{1}{url}
  \stopTEXpage
  \stoptext

How could I make this sample or a similar approach work?

What I need it to avoid entering the same address more than once.

Many thanks for your help,

Pablo
