I want to send a request to a server to download a file. However, when the file is sent by the server, I don't want to actually receive the file. I'm trying to see if it's possible for me to overload a server's bandwidth without having to actually download files.
I'm guessing this should be possible using some sort of a UDP protocol where no acknowledgements are required.
If the download is available via HTTP GET, you can try sending an HTTP HEAD request with the same headers to try to receive a response without the server actually sending the file.

Is there a way for Squid Proxy to intercept and filter HTTPS payload from request made before it is being sent? Just like the way mitmproxy does.
I found out it's possible to log the payload with ssl-bumping, I had some success also altering response data with sample ecap. Only if I knew some C programming.
Also, iptables has a function to filter payload by string but only with http traffic. I don't know if it's possible to strip the SSL traffic first before feeding it to iptables and send the request outside before sending back (mitm proxy basically).
The only drawback with mitmproxy right now is unable for daemonization (you need to hack it), and I have my doubt using it in a large load.
Any one way or another?
I would like to monitor the performance of my server by sending a POST request with a file to upload to the server. Can you please tell me what is the option I should add?
Thanks!
This questions was asked during one of the interview. How to transfer data from one server to another using AJAX? Is it really possible?
AJAX is generally used on the client side, not usually the server side.
It sends requests to a server.
You probably need to provide more information about what you are trying to achieve to get a decent answer.
If you are wanting to transfer data from a "client" to a server then you could send the data in a variety of ways - especially with AJAX. Just how depends on what data type and size. Requests from a client to server (HTTP) can include POST data, which can carry your data to the server.
If you are using AJAX on a client and wanting to use it to transfer data from one remote server to another then you could get AJAX on your client to call a script on the server that would instigate the transfer from the server to another server in some way. (such as FTP or SCP maybe - or even using a server to server HTTP POST)
If you can be a little more specific about what you need to do then I will try and give you a better answer.
I want to implement a Client-Server program in which the client has to send a file to the server. In this case, what is the efficient way to send the file to server?
I am thinking in the following method,
After the connection establishment, First, I have to send the file name (which i want to upload) to server from client. Then I have to send the file content to server. The server will wait for the file content after received the file name from client.
So, for uploading a file, I need 2 write method in client & 2 read method in server.
Is this ok? Is there any other efficient way for doing this?
I think that your idea is correct. Maybe you should consider not to send files name (only the extension line .jpg) and let server generate one. This will prevent overwriting some already existing files.
Is there a program available that will allow me to interactively write HTTP stream data and send it to a server? Ideally I'm looking for a console app that will allow me to type or paste HTTP headers and body, send it to my server, and get the response headers and body back.
Does such a program already exist?
I'm running W7 64-bit with .NET 4.0.
if you change your mind and want a GUI app
http://code.google.com/p/rest-client/
or you can also use fiddler
Edit:
http://code.google.com/p/rest-client/ also supports commandline
Maybe telnet is an option for you? If it's not already installed on your machine, take a look at this guide from MS.
To connect to your server use it like this:
telnet www.myserver.de 80
After the connection is established, you can paste your HTTP GET reqests or what ever you like.
tinyget is a useful MSFT tool that will make simple get requests. You can store these requests in text files and stream them in.
