The problem is that with this line:
  my @answer = <$socket>;

you are saying to Perl to read in the whole "file", so of course it won't return until the socket is closed. Your protocol needs to have some way to tell when your server has finished talking. There are lots of ways to do this, you just have to make sure that your data won't accidentally trigger that condition.

Common ways are to:

  1. prefix the response with the length of the data
  2. or, send a blank line when you're done
  3. or, send a dot on a line by itself
  4. or, prefix each line with some character that indicates whether or not it's the last line
