I have written a handler for delivering select images for a particular
class of URIs based upon a database item that the user sets in advance.
This allows us to "skin" some HTML allowing the user to select their look
of choice.
The problem I have is that IE5 (and perhaps other browsers and versions)
but NOT Netscape 4.x have absolutely no respect for cache-control.
My code does this:
$r->no_cache(1);
# some code to calculate a date 10 years ago (!) goes here...
$r->header_out(
'Expires' => "$day_text, $day $mon_text $year $hour:$min:$sec GMT"
);
$r->send_http_header($subreq->content_type);
And the HTTP headers via Lynx look like this:
HTTP/1.0 200 OK
Date: Fri, 26 May 2000 08:58:38 GMT
Server: Apache/1.3.12 (Unix) mod_perl/1.23
Pragma: no-cache
Cache-control: no-cache
Expires: Tue, 29 May 1990 1:58:38 GMT
Content-length: 1332
Content-Type: image/gif
But IE5 still caches the damn things! Does anyone have a suggestion?
Please note that I don't have the ability to modify the IMG SRC
dynamically since the HTML resides on our customers' servers.
