webserver - node.js front end web server -


i have seen lots of posts people recommending nginx or similar front end web server node.js.
since node has ability create web server, such as:

var http = require('http'); var static = require('node-static'); var file = new static.server(); var url = require('url');  var index = require('./serverjs/index.js'); var login = require('./serverjs/login.js'); var admin_index = require('./serverjs/admin_index.js'); var admin_login = require('./serverjs/admin_login.js');  http.createserver(function (req, res) {     if (url.parse(req.url).pathname == '/index') {         index.serve(req, res);     } else if (url.parse(req.url).pathname == '/login') {         login.serve(req, res);     } else if (url.parse(req.url).pathname == '/admin/index') {         admin_index.serve(req, res);     } else if (url.parse(req.url).pathname == '/admin/login') {         admin_login.serve(req, res);     } else {         file.serve(req, res);     } }).listen(9000 , '127.0.0.1' );


q: in case scenario need web server in adition node's?

a front-end nginx more efficient @ serving static assets.

a front-end nginx useful if wanted run multiple backend servers, node.js combined apache/php node.js serves routes , apache/php serves other routes.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
