Subject: Requests using If-Modified-Since cause response Set-Cookie to be

I have PerlAuthenHandler handler that sets a cookie on authentication
success. The cookie records, in part, the time of the last access to
the site. Therefore for each access the cookie is updated. When a new
document is accessed or a CGI script is run the cookie is sent to the
browser. However, if the browser is asking for a document it has
cached it will send an If-Modified-Since header. The file delivery
mechanism in Apache will do the right thing with If-Modified-Since
information and only send the document if, in fact, it has changed.
Unfortunately, if it has not changed the cookie I set in my handler is
discarded (no matter if I use $r->header_out() or

How can I force Apache to send the Set-Cookie header even if the
document being delivered has not changed? I suspect that I am not the
first person to run into this problem. A search of the list was
unsuccessful, unfortunately.
