Hello,

I have a problem with last modified header in oscache.
All the images in my website are database images. Because I won't query the database for the same images, I made a filter and mapping in my web.xml.

<filter>
    <filter-name>Set Image Cache</filter-name>
    <filter-class>com.opensymphony.oscache.web.filter.CacheFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>Set Image Cache</filter-name>
    <url-pattern>/db.images/*</url-pattern>
  </filter-mapping>

This works fine. But the last modified header are only showed at the first request.

First time:
HTTP/1.x 200 OK
Last-Modified: Fri, 05 Dec 2003 09:54:02 GMT
Date: Fri, 05 Dec 2003 09:54:02 GMT
content-disposition: inline; filename="tv portal.jpeg"
Expires: Sat, 06 Dec 2003 09:54:02 GMT
Content-Type: image/jpeg
Content-Length: 23182
Server: Apache Coyote/1.0
Connection: keep-alive

Second time:
HTTP/1.x 200 OK
Content-Type: image/jpeg
Content-Length: 23182
Date: Fri, 05 Dec 2003 09:54:02 GMT
Server: Apache Coyote/1.0
Connection: keep-alive

So, the browser couldn't cache my images.

What's the problem here?
