overriding mod_proxy headers with mod_expires

[WHIRLYCOTT <phil@xxxxxxxxxxxxxx>]

I have Apache 2.2.3 going against a servlet engine.  I have some  
static content that is hosted by the servlet engine (css, jpegs,  
etc.).  Whenever a request without a JSESSIONID cookie hits the  
servlet engine, the servlet engine sends back a Cache-control: no- 
cache header and an Expires header specifying the epoch (i.e. Jan 1  
1970) along with a Set-Cookie header that contains a new JSESSIONID  
cookie.

What I want to do is configure mod_expires (and/or mod_headers) to  
effectively ignore what my servlet engine says and override the  
Expires and Cache-control headers with something far in the future and  
remove the Set-Cookie header that originates on the servlet engine.

With mod_headers, I can remove the Set-Cookie header.  In fact, with  
mod_headers, I can pretty much do what I want except use mod_expires  
lovely syntax for specifying expiration dates (i.e. "access plus 30  
days"), which is fairly important to me.

So am I missing something or is it indeed the case that I cannot make  
mod_expires override what is coming back from the proxied request?
