[jQuery] Problem with $.post()

[jQuery] Problem with $.post()


Hi
When I'm using $.post() on Lighttpd - all is ok. But I try to use it
on Google App Engine server and it return 411 error (Content Length
required). What is wrong? This is my code:
$.post("/my/url/", { entry_id: 5, body: 6 }, function(json){
        // some operations with result
}, "json");
Please, help me. And sorry for my English.
