Hi,
Expiration headers seem to be ignored by Internet Explorer behind a Proxy server when using BACK / FORWARD buttons. On Microsoft's Knowledge Base Article 234067 (HOWTO: Prevent Caching in Internet Explorer) I've found that in fact this can happen. And I could verify that, behind a Proxy, IE (6.0, 5.5, 5.0) gets the page from local disk cache although Expire = -1 header should force it ask the web server for an updated version.
The only workaround I've found was to place dynamic pages in an https:// environment where (Pragma, no-cache) header prevents IE from storing in local cache the response.
Any better ideas ?

Thanks very much in advance.
Regards,
