Calling a controller method asynchronous

[eluser]Unknown[/eluser]
Hi,
i have following problem: I need to call a function in one of my controllers asynchronous, so that this code is evaluated in background. I dont want to use a cronjob, so i tried to do it with curl or fopen, but all methods return a 404 page not found error. I dont know how to solve this problem. I also thought of using ajax, but don't know how to implement it. My code structure is at follows:

- When the submit-button is pressed, a database entry is created which contains a counter
- Now the script has to call the asynchronous method, which loops until it reaches the counter and processes data
- While the data is processed, the user should get back to the user interface to interact with the webpage; there is also a page where he can see the progress of the data performing; the return to the interface should be immediately, so that the method call don't blocks

But it doesn't work. Is there a simple solution?

Unfortunately PHP doesn't allow/support multithreading.

Hmm, i tried the method once before, but this one looks better. Unfortunately i get a HTTP 302 Page Found response, but nothing more. Crazy thing...

This is the result from the GET:

Which means you get a HTTP redirect in return.
