I did a simple jsp page as you suggested to test with a Struts action that returns to the same page:
The first time I access the page the SSI is at the top as expected. Once I go through the action and the jsessionid is in the URL I don't see the SSI. If I manually remove the jsessionid from the URL it is back again. (I have cookies enabled.)
The only difference is ;jsessionid=A50BC28A812D3F20500898AC44C02ADF is appended to the URL in the second case. Also I am using Apache to process the SSI instead of Tomcat/Jboss.
