node.js - Easiest way to persist/cache a web response -


i'm playing node.js. using http-proxy, want create simple web proxy makes request , stash response somewhere before passing response. if detect no internet connection or flag set somewhere, want replay response have stashed away. url "key" , entire response "value".

my question is, what's easiest way serialize response object can replayed later? looking @ mongodb , mongoosejs, i'm put off because mongoose wants me create schema object, , want dump entire response object somewhere (with url key). there easier way?

here's super simple node.js proxy code:

var httpproxy = require('http-proxy');  var server = httpproxy.createserver(function (req, res, proxy) {    var buffer = httpproxy.buffer(req);    proxy.proxyrequest(req, res, {     host: 'url.to.proxy.com',     port: 80,     buffer: buffer   }); });  server.proxy.on('end', function (req) {   console.log("the request proxied.",req.url); });  server.listen(8000);

the easiest way store response object in file; don't need database.

  1. create response object cache directory.
  2. hash url using sha-256 , use result file name.
  3. stream response object to/from file.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
