I'm using Struts with Tomcat 4.1. If you disable cookies in your tomcat context, all your ULR will be rewritten with a jsessionid. So the proxy issue should be solve. However I don't know If there is a way to enable cookies AND be sure that the proxy's cache is disable.
In my project I use this in all jsp I won't be in any cache :
<%
response.setHeader("pragma", "no-cache");
response.setHeader("Cache-control", "no-cache, no-store");
response.setHeader("Expires", "0");
%><head>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
</head>It seems to work for me but I'm sure there are more élégant solutions. Using Struts, you see on the <bean:header> tag. I still haven't found time to explore it. Let me know if it's work for you.

Hi all !
My application is running behind a proxy which caches everything, if the url is the same.
It's no use that I have this in each Jsp:
<meta http-equiv="pragma" content="no-cache">
Therefore I used the Struts-property
<controller nocache="true"/>
But it was not that I expected:
My Login-Site has this URL:
http://localhost:8080/lager/Welcome.do;jsessionid=0146C3084A50F84EDEE81FE78E E56DAE?action=toLogin - is ok.
But when I make login, the next URL has no jsessionid:and therefore it is always the same:
http://localhost:8080/lager/Login.do?action=makeLogin
Is it possible to avoid proxy-caching with Struts by changing each URL with appendig a random-number or such a thing ?
Please give me a tip.
Thanks in advance for your help.
Best regards.
Christine
