http - Implementing a WebServer -


i trying create web server of own , there several questions working of web servers using today. questions are:

  1. after receiving http request client through port 80, server respond using same port 80?
  2. if yes while sending large file pic in mb's, webserver unable receive requests other clients?
  3. is computer port duplex or simplex? (can send , receive @ same time)?
  4. if port on server side used send response client, (if tcp used, used), again 3-way handshaking done overhead...

http://beej.us/guide/bgnet/output/html/singlepage/bgnet.html here guide on what's going on webservers, although it's in c concepts there. explain whole client server relationship implementation details.

i'll give high level on what's going on: happens when server gets new request comes in creates fork process it, way not bogged down each request, when request comes in child process handed new file write to(again implementation details).

so have 1 server waiting requests , each request received spawns child process deal request. i'm sure there easier languages implement stuff c(i had both c , java server serving either 1 in past) c gets understand things going on , i'm betting looking here

now there couple of things think about: how want webserver work. example explains parent child process. want use tcp/udp there differences in way payload gets delivered. don't have connect on port 80. that's default web.

hopefully guide you.

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...
