Question: I store session parameters in a Struts2 session map that I get in my actions using the SessionAware interface. My Application is in the /MyApp path.

After setting up the struts2 application on an Apache server with an inverse proxy redirect that makes the URL **<http://www.appdomain.com/>** point to my local tomcat on **localhost:8080/MyApp**, Struts2 session handling doesn't work anymore. I expect that the session cookies are stored for the Struts2 context of <http://localhost:8080/MyApp> instead of <http://www.appdomain.com/> ...

Is there a solution in Struts2 configuration? Or in programmatically changing the session cookie somehow? Couldn't find any info about this on the interwebs or in the official documentation. Please help, I'm already in production and my logins don't work ;-)

Answer: 
I just solved the problem with a dirty hack: I passed the Session Id to the JSP and use a javascript to set the needed JSESSIONID cookie clientside.

 function createCookie(name,value,days) {
 if (days) {
 var date = new Date();
 date.setTime(date.getTime()+(days\*24\*60\*60\*1000));
 var expires = "; expires="+date.toGMTString();
 }
 else var expires = "";
 document.cookie = name+"="+value+expires+"; path=/";
 }

$(document).ready(function() {
 createCookie("JSESSIONID","",3);
 });

Got the JS code from this page: <http://www.quirksmode.org/js/cookies.html>

Thank you, problem solved!

Put this in your `httpd.conf`

```
#all cookies from /MyApp are proxied to "/"
ProxyPassReverseCookiePath /MyApp /

```
