Plain text please...

There are three directives which begin Expires***. Look in the docs and =
you'll see them. These allow you to define a header using the apache =
module, mod_expires. If you want to use some other method to generate =
the headers, that's fine, but remember that this is an apache mailing =
list - not a general HTTP help-line, so you'll need to look elsewhere =
for support.

Rgds,
Owen Boyle

Hi Boyle,=20
Thanks for your comment!  I have looked at the "ExpiresXXXX" directive, =
but I thought that this was only if I were to use the Apache =
configuration file to generate the HTTP header.  Since I'm not using =
that, do I still have to load mod_expires?  Maybe I'll try both and see =
what happens...=20
Thanks,=20

Have you looked at the "ExpiresXXXX" directives? You need to load
mod_expires but then this gives you a standard interface to generate
Expires headers.=20

Be aware that, although you may generate whatever headers you like, the
browser or proxy which is doing the caching is under no obligation to
obey them.

Subject: [users@httpd] Expires HTTP Header


Hi all,
I am using Apache server version 1.3.26. I use CGI scripts (Perl) to
append to the HTTP header. Basically, I don't want my HTML pages to be
cached at all. I tried this method,=20
print "Content-type: text/html \n";
print "Pragma: no-cache \n\n";
and it works! However, I heard th! at using Pragma is not good, so I
tried using the Expires HTTP header,
print "Content-type: text/html \n";
print "Expires: Fri, 30 Oct 2002 14:19:41 GMT \n\n";
However, the page is still cached. Do you know why this? Do I need to
install the "mod_expires" Apache module?
Thanks for your help,
Monica
