Hi Amos
Thank you for your reply. I believe this is good solution.
But after I made the change below in my custom web page:
snprintf(buf, 128, "X-Infection-Found: Type=0; Resolution=2; Threat=URL;");
buf[127] = '\0';
ci_request_add_xheader(req, buf);
snprintf(buf, 128, "Cache-Control: cache-request-directive=no-cache;cache-response-directive=no-cache;");
// i tested snprintf(buf, 128, "Cache-Control: //cache-request-directive='no-cache';cache-response-directive='no-cache';"); also.
buf[127] = '\0';
ci_request_add_xheader(req, buf);
snprintf(buf, 128, "Expires: -1;");
buf[127] = '\0';
ci_request_add_xheader(req, buf);
my custom web page is still kept displaying . Any comments?
Thank you.

Have your custom ICAP service set the cache-control headers properly in
the custom page. Expires: with the current time or a few seconds in the
future should do it.
