Calling BSP with AJAX does not work

Hello,

i'm trying to send formular data via ajax to an bsp page.

The problem is, that the bsp site does not even start 😔

here is my ajax part from the html page:

url = 'kommentar_id=' + comment_id + '&comment=' + escape(document.getElementById(my_id).value);

http_request.open('POST', '/sap/bc/bsp/zre_kommentare2/kommentar_speichern.htm', true);
http_request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
http_request.setRequestHeader("Content-length", url.length);
http_request.send(url);

In the onRequest event of the bsp page i have an infinite loop. But there is no process in SM66 when i submit the html formular.

When i use the GET method, the bsp page is called, and there is a process in the infinite loop.

Result: when i use GET, it works

when i use POST, it doesn't work 😔

Any ideas ?

Regards,

Tobias
