Generate http request

Hello guys,

I want to create a simple program that will test my server. It should send multiple requests for some file (.html, .php, .jpg ...) but it would be able to generate and send at least couple of hundred of those IN A SECOND!

I tried using Webbrowser control... well its kinda slow, plus the most i got out of it is probably 5 request per second may be a little more once in a while.

So I would assume I have to have like an array or a collection of those requests READY to be send in one instant.

I'm not trying to develop a next SPECweb2005 here but the general idea is the same.

Appriciate all the help!

p.s. either vb.net or classic vb is fine with me.

Sounds like a DoS attack program...

Re: Generate http request

doesn't the microsoft application test center in MSVS 2003 do just what you're requesting?

You could try looking at System.Net.WebClient and System.Threading as a start...

Create multiple threads that all have an instance of WebClient and make requests over and over again to a server.

Hope this helps,

OK, thank you for the hint. :thumb:

I created some simple app, it creates whatever number of threads I need that send http requests.

Now I can have a lot more requests PER second but it still not enough for the project.
Is it possible to create lets say 1000 Threads that will send a request but not start them untill all of them are created and then start all of them at once but not one by one? :cool:

I'm not very good with thread synchronization and such, but my immediate thought is have a loop at the beginning of each thread method that waits for a global boolean to be set to true, and set the global to true after all threads are created...

that's what i was thinking as well, but the thing is:
if i created 1000 threads BUT not start them, I will have to go through a loop anyhow to start all of them and it will take time as well...

if you open the vs 2005 IDE with no solution or projects, one of the menu selections is Test.
I believe this is where microsoft moved their application test environment.
