Redirect to the same application arriving before data in session saved

I save some data to http session, then send a redirect to another page in same application. In the next page (Servlet) I try to read the data from the session, but this data is empty.
Code is similar to this:

     session.setAttribute("myAttribute", "<data >SomeData</data>");

Now when next servlet is executed, session.GetAttribute("myAttribute") does not return data I have just saved.
In order for the next page to display correctly, I need the data from the session.
How to avoid redirect coming to server before the original code ends writing data to session?

if it is in the same application then use
.forward rather than redirect.

Can't do forward. I need the browser to be set to the new URL, so if user reloads the page, he reloads new URL, not original one.

If your urls are in the same application, then they should be able to share the session... Try printing the session ids at both points..

i.e. at first servlet before redirect and then at second servlet after redirect.

They do share the same session. I think that the problem is that under some circumstances browser redirect arrives at server before session.setAttribute was executed.
