Question

I build a Web Server in java, which I get request (as a socket) and process it.
I am required to first print the entire request and then process it on.
Here’s my code snippet:

public HttpRequest(Socket socket) throws Exception
{
    this.socket = socket;
    BufferedReader input = new BufferedReader(new InputStreamReader(socket.getInputStream()));
    printRequest(input);
    // Do More...
}

The problem is that from this point on, the BufferedReader is in its end and I can’t seem to find a way to get it back to the beginning. The printRequest() method prints the entire request from the BufferedReader with a while loop and readline() actions).

Any ideas how I can fix this?

You can read the content in a byte array, and then use ByteArrayInputStream any time you neeed it:

InputStream is = socket.getInputStream();
byte[] content = new byte[is.available()];
is.read(content);
printRequest(new BufferedReader(new InputStreamReader(new ByteArrayInputStream(content))));
processRequest(new BufferedReader(new InputStreamReader(new ByteArrayInputStream(content))));
