video75 can be used to search youtube videos in countres like turkey, where youtube is banned. I observered the request and response from video75 and saw that it ultimately streams the video from googlevideo cache . I tried to play a video on video75 and I saw that ultimatly video was coming from

http://v3.cache8.googlevideo.com/videoplayback?ip=0.0.0.0&sparams=id,expire,ip,ipbits,itag,burst,factor&itag=5&ipbits=0&signature=C828978445F6F8FAC364767190EA41EDB026A90F.D05B9AF70E9A BCD458456D5D5E772D6B6612CC98&sver=3&expire=1250175600&key=yt1& factor=1.25&burst=40&id=0dcfc8d7fb303089&redirect_counter=1

the abobe url. How does video75 searches the video in the googlevideo cache.? IF i try play a video on youtube then the video is ultimatily streamed from chacheXX.youtube.com

how can i get a googlevideo /gooogle cache of a video which corresponds to a youtube video url /cache url?

I think you misunderstood my question . I want to make a proxy server. Clint pc onccnet to my server .My server to youtube.
clintpc - my server - youtube

So here my srver is trying to download the video from youtube and trying to deliver it to clint in realtime

Can i use the following code in a applet
System.setProperty("http.proxyHost", "220.134.110.231"); System.setProperty("http.proxyPort", "80");

I want to direct all traffic to and from applet via some proxy server.

MEans when any person visits my website, the applet along with the webpage shod go to the clint side. And all data to and from applet should go throught the proxy.

Youtube is banned in turkey. So i want to write a web application in j2ee via which people of turkey can sracrh /dowload and play youtube video. that is i want to devlop website similar tovideo75.com. I am uisng the following servlet. But what happens is that it doesnot stream the video as such. It only gets the player and one video screenshot to clint side. Then this player tries to download video from youtube.com. The moment the player tries to access youtube.com it gets blocked , as youtube is banned in turkey.So waht i want is that i want the whole video and other traffic to go through my site. I am currelyly using google data api to search youtube video. But whihile playing the player tries to get the data directly form youtube

How can i make the entire traffic go through my servre??

Currenly i am using a servlet. and one jsp

i have following line in jsp
<iframe src="/MyWebApplication/TestServlet"></iframe>
this is i am only caling the servlet in iframe

the follwing is my servlet code
/* * To change this template, choose Tools | Templates * and open the template in the editor. */ package com.test; import java.io.BufferedInputStream; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.io.PrintWriter; import java.net.InetSocketAddress; import java.net.Proxy; import java.net.SocketAddress; import java.net.URL; import java.net.URLConnection; import javax.servlet.ServletException; import javax.servlet.ServletOutputStream; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * * @author akshay */ public class TestServlet extends HttpServlet { /** * Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods. * @param request servlet request * @param response servlet response */ protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // System.setProperty("http.proxyHost", "220.134.110.231"); // System.setProperty("http.proxyPort", "80"); ServletOutputStream outputStream = null; URL url = new URL("http://www.youtube.com/v/3y49IXavVDE&f=standard&c=gdataSample-YouTube-1&app=youtube_gdata"); // SocketAddress address = new InetSocketAddress("220.134.110.231", 80); // Proxy proxy = new Proxy(Proxy.Type.SOCKS, address); // URLConnection connection = url.openConnection(proxy); URLConnection connection = url.openConnection(); int contentLength = connection.getContentLength(); String contentType = connection.getContentType(); String encoding = connection.getContentEncoding(); response.setContentLength(contentLength); response.setContentType(contentType); System.out.println("MimeType->"+contentType); System.out.println("Encodeing->"+encoding); System.out.println("ContentLegth->"+contentLength); byte[] buffer = new byte[contentLength*4]; BufferedInputStream in = new BufferedInputStream(connection.getInputStream()); try { outputStream = response.getOutputStream(); int inputLine; while ((inputLine = in.read(buffer)) != -1) { outputStream.write(buffer, 0, inputLine); } outputStream.flush(); outputStream.close(); } finally { if(in!=null) { in.close();} } } // <editor-fold defaultstate="collapsed" desc="HttpServlet methods.

why is no one replying?

i want to implement a proxy server in java. Is there any open source proxy server implemedtiaon in java. I was using the following code. I have to classed . One is main and other is ProxyserverThread. Will this code will be able to handel lots ot traffic if i deplaoy it for real use?? Is this approach right?? Also i want to replace some url with the new one.
