Hello, I'm so sure it's a Zope question or not, if I'm wrong, sorry for wrong post. I had looked up the answer for a long time,but still have no answer for this strange thing. We use Apache and Zope combination on Linux as web server(behide in DMZ), we store most images on file system, then use rewrite rule to rewrite the request to local file system for images, others go to Zope. But the Internet Explorer could not successfully view the image, while the other browsers(Mozilla) are working fine. the access.log said "GET /images/2004/02/26/thumbs/20040225204655.jpeg HTTP/1.1" 304, mean the image had cached. http.conf RewriteEngine on RewriteLog /var/log/rewrite.log RewriteRule ^/images/(.*) /home/httpd/images/$1 [L] RewriteRule ^/(.*) http://www.taipeitimes.com:9673/VirtualHostBase/http/www.taipeitimes.com:80/... [P,R] If you want to try,browser by Internet Explorer on http://www.taipeitimes.com/News/photo/2004/02/26 or different date http://www.taipeitimes.com/News/photo/YYYY/MM/dd Thanks for your time, and passion :o) Terry
