Usually the ways of reading a file in Ruby are higher level, where the
EOF is handled for you:

content = File.read("file.txt")
content = File.readlines("file.txt")
File.foreach("file.txt") {|line| content << line}

and so on.

What are you trying to do?

             Am looking to configure mongrels's http_request.rb in
order to
delete mongrel temporary file after upload .This is what i would like to
have

def initialize(params, socket, dispatchers)
      @params = params
      @socket = socket
      @dispatchers = dispatchers
      content_length = @params[Const::CONTENT_LENGTH].to_i
      remain = content_length - @params.http_body.length

      # tell all dispatchers the request has begun
      @dispatchers.each do |dispatcher|
        dispatcher.request_begins(@params)
      end unless @dispatchers.nil? || @dispatchers.empty?

      # Some clients (like FF1.0) report 0 for body and then send a
body. This will probably truncate them but at least the request goes
through usually.
      if remain <= 0
        # we've got everything, pack it up
        @body = StringIO.new
        @body.write @params.http_body
        update_request_progress(0, content_length)
      elsif remain > 0
        # must read more data to complete body
        if remain > Const::MAX_BODY
          # huge body, put it in a tempfile
          @body = Tempfile.new(Const::MONGREL_TMP_BASE)
          @body.binmode
        else
          # small body, just use that
          @body = StringIO.new
        end

        @body.write @params.http_body
        read_body(remain, content_length)
      end

      @body.rewind if @body
    end

Here i would like to close this @body after use by using something like
@body.close but while doing so am getting error what should i do and
whre should i call this @body.close
i am looking to close @body after eof reached
