Redirects with ant-contrib post task

Hi,

I am trying to post data to an API say http://localhost/save which in turn calls create or update based on whether the passed id exists in Database or not.
<post to="http://localhost/myapp/save?id=2167"
        verbose="true" file="C:\test.properties">
</post>

Problem is when i hit save with above code which is one action save,based on input since it gets redirected to action create or update session is getting lost so it always creates a new record.

Is there any task which could help me on this issue?i had a look ant ant-fikin-tasks also

Regards
Raju
