ruby - Rails HTTP Ping to unreliable Target -


i send http request ip address , port determine if there device online can respond @ address.

i want have relatively reasonable timeout application not hang while connecting, if there's no. have been using net::http, there not seem way set timeout when using ip address.

res = net::http.get_response(ip_address, '/index.html', port)

is there best practice or better method perform request or way set timeout in net::http when using ip address rather domain name?

i'm using ruby 2.1.5 , rails 4.1.0 hosting on heroku.

there's no major difference between requesting via ip address or dns name, in latter case dns query made , host-header set, after request done via ip.

in net::http there's open_timeout setting raises net::opentimeout when set if connection cannot established during period. default it's nil means 'forever'

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
