How to test how many clicks my site can handle at once?

I tried many different stress test software such as loadimpact, webserver stress tool, but they don't literally click on my website.

I have a site that once the user clicks on it, it will send a post command using jquery and then that gets recorded.

I want a test to have 100 users literally click on my site at the same time to see if it will record all those clicks in my post command.

Is there any program out there that can literally generate 100 clicks on my site for a test ?
