HTTP Stuff

[abc]

hey uh, I'm trying to setup an automated login for a website and I've been packet logging the login I've been coming across some problems.

I see

Code: [Select]

Host: secure.somesite.com\r\n
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1\r\n
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n
Accept-Language: en-us,en;q=0.5\r\n
Accept-Encoding: gzip,deflate\r\n
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7\r\n
Keep-Alive: 300\r\n
Connection: keep-alive\r\n
Referer: http://www.somesite.com
Content-Type: application/x-www-form-urlencoded\r\n
Content-Length: 682

My question is, when sending this information, do I have to send it in the exact order for it to work?

I'm programming in C# using the HttpWebRequest

These are HTTP headers, so order isn't important.

Use HttpWebRequest.Headers.Add(string name, string value) before you send the request.

thanks for the clarification Sidoh.

Using HttpWebRequest, you don't need to worry about all that.  You just need to manage the Content-Type and the contents.  You can also hack User-Agent if you want to spoof a browser.

alright cool, that's what I've been doing

Code: [Select]

        req.Method = "POST";
            req.UserAgent = "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1";
            req.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
            req.Headers.Add("Accept-Language: en-us,en;q=0.5");
            req.Headers.Add("Accept-Encoding: gzip,deflate");
            req.Headers.Add("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
            req.KeepAlive = true;
            req.Connection = "300";
            req.Referer = "somesite.com/whatever";
            req.ContentType = "application/x-www-form-urlencoded";
