Send HTTP packets without a browser?

I have two questions:

  • I am trying to send an HTTP request to a web server without using a web browser. I read that the most common way to do this is with Telnet, but I wondered about other ways.

  • Also, I think my telnet has a problem. I activated the telnet client and went to the command window and dialed telnet, then dialed “open IP address 80” and it says “connect to IP address ...” forever, but never lets me get past this. Have any of you encountered this problem? In addition, I noticed in Wireshark that the TCP handshake is happening correctly.

Please thanks!

You should also check out the curl command-line utility: http://curl.haxx.se/ Basically, this is a cool little piece of software that handles HTTP requests (and also supports other protocols). Also check out hurl: http://www.hurl.it/ , which is a kind of web application freeze version.

Did you specify the port? Port 80 is commonly used for HTTP requests.

telnet www.some-site.com/some-page.html 80

Once you are connected, you need to make a GET request. (Send a GET command).

You can accomplish the same thing using sockets or WebClient (C #):

By default, Telnet used:

At the telnet command line, you can do:

  o host port> (o www.website.com 80) GET /index.htm HTTP/1.1

Using WebClient (Note: this is a WebClient C # object):

  var webClient = new WebClient(); webClient.Headers.Add("user-agent", "Agent"); Stream responseStream = webClient.OpenRead("http://www.google.com")

The response from the server will be stored inside the responseStream object.
