HTTP/1.1 400 Bad Request, why?

Hi, I've been working on my first network asst for some time now, but I get HTTP/1.1 400 Bad Request every time. (i've tried many other website, too)

code:

public void checkAddr(String aPath, String aSrv)     {   srvN = aSrv;         pathN = aPath;                 try         {   Socket clientSocket = new Socket(srvN, portNum);             DataOutputStream outToServer = new DataOutputStream(clientSocket.getOutputStream());             BufferedReader inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));                         c_s = "GET "+pathN+" HTTP/1.0"+'\r'+'\n'+"HOST: "+srvN+ '\r'+'\n';             System.out.println("write to client out socket, the line is: "+'\n'+c_s);             outToServer.writeBytes(c_s);             System.out.println("wrote");             s_c = inFromServer.readLine();             System.out.println("got response");             System.out.println(s_c);             clientSocket.close();         }         catch (Exception e)         {   System.out.println ("socket creation fail");         }     }

should I not be using socket or something? these are the exact code format I took from the class lecture.


I always get (everything before the response was my debug statement)

write to client out socket, the line is:
GET / HTTP/1.1
HOST: bbcr.uwaterloo.ca

wrote
got response
HTTP/1.1 400 Bad Request

Try using a higher level library. There is likely a mistake somewhere in there in your codes, and the higher level libraries don't have it. And by higher level, I mean one where you go Connect(website)->string containing html.

Try changing HOST: to Host:
and I'm not sure if CRLF is the same as LF in http, so try without the \r 's as well.

Ensure that your HTTP request ends with a sequence of "\r\n\r\n". Otherwise web-servers will ignore your requests.
