IE6 Download Issues Over SSL

From http://support.microsoft.com/default.aspx?scid=kb;en-us;812935#kb3

When you try to open a Microsoft Office document or a PDF file by typing an HTTPS Uniform Resource Locator (URL) for the document on the Address bar in Internet Explorer 6 Service Pack 1 (SP1), the document may not open, and you may receive the following error message: Internet Explorer cannot download document.pdf from server

The following forum issue extract describes how you can disable the Cache-Control header which causes this problem.

jboss-3.2.6+ supports a WEB-INF/context.xml descriptor that allows one to customize a war context. The custom valve would be added by including a myapp-web.war/WEB-INF/context.xml with:

 
<Context> 
<Valve className="org.apache.catalina.authenticator.FormAuthenticator" 
disableProxyCaching="false" ></Valve> 
</Context> 

With this the headers for the jmx-console secured using form auth look like:

 
http://localhost:8080/jmx-console/ 

GET /jmx-console/ HTTP/1.1 
Host: localhost:8080

Without this or with the disableProxyCaching=true there are Pragma: No-cache and Cache-Control: no-cache headers in the replies:

Alternative solution

An alternative is to manually override the Pragma and Cache-Contol response headers:

 
response.setHeader("Cache-Control", "cache, must-revalidate"); 
response.setHeader("Pragma", "public");
