Errata: this is not the code which is used to make request, but to call js.
Request are simple GETs or POSTs sometimes with attached files, they talk with
servlet.
When requests are done, js is called from applet with success, but for some
reason I get StalePageException in the request listener if in the final stage
of applet thread three requests are done. When applet makes only one request in
the final stage, everything is fine.
Simplest example of request which is used:
URL url = new URL(getDocumentBase(), spec);
HttpGet get = new HttpGet(url.toURI());
get.addHeader("Cookie", getCookie());
HttpResponse response = client.execute(get);
String responseText = EntityUtils.toString(
response.getEntity() );
