Headers apache win32

Hi all:

        I have apache server 1.3.22 + php 4.1.1 + win32. Our clients (other networks) goes internet througth a proxy server. I like then not to cacheing pages.

        I have tried uncomentting the lines:

                LoadModule expires_module modules/mod_expires.so
                LoadModule headers_module modules/mod_headers.so

                AddModule mod_expires.c
                AddModule mod_headers.c


        Also I wrote:

                header set Cache-control "private,no-cache"

        And restart the apache service. But the clients continuing cacheing pages. What can I do?. How can I know loaded modules in apache win 32?

            I need clients not cacheing pages.

Thank you.

Finally putting in httpd.conf the line

header append Cache-control "private, no-cache"

The proxy does not cacheing the pages. The new problem is that now its
imposible to download zip files from the web although existing in the path.
Solution one proble other problem appears.

You can make suggestions to the clients.  The clients make the final
decision.

See mod_expires, mod_headers and the HTTP/1.1 specification.

No, as has been stated several times, the client or proxy can do whatever it
wants.  However, this configuration does suggest to clients and proxies that
they shouldn't be caching.  And I believe that an HTTP/1.1 compliant browser
would be forbidden from caching, but you should check the specification to
be sure.

Hmmm, does Win32 Apache have -

#
# MetaDir: specifies the name of the directory in which Apache can find
# meta information files. These files contain additional HTTP headers
# to include when sending the document
#
#MetaDir .web


???

In the httpd.conf

1 .-Putting the lines

                                Header Add Expires 0
                                Header Add Pragma no-cache
                                Header Add Cache-Control no-cache



uncomenting de lines

                                AddModule mod_expires.c
                                AddModule mod_headers.c
                                LoadModule headers_module
modules/mod_headers.so
                                LoadModule expires_module
modules/mod_expires.so

2 .-And restarting httpd server is suficcient to avoiding client caching via
proxy server?

All under win32+apache 1.3.22.

PMFJI - while I apologize for my last post - this too is only a 'suggestion'
as made by the server; the client doesn't have to honor it.


I vote we all just write our own clients!

Please don't use non-standard, browser-specific stuff like that when you can
easily add

Header Add Expires 0
Header Add Pragma no-cache
Header Add Cache-Control no-cache

to httpd.conf.  HTTP Headers should be sent as HTTP Headers, not inside
HTML.

LOL :)  He said 'not let'  :)

My client will do what *I* say - not what a remote server says (if it didn't
then I wouldn't use it)  :)

I call it 'C/S Security' and some developers (maybe not many) do still
believe it should work a certain way :)

Cheers!

I believe these header tags will not let clients and search engines cache
your pages

<META HTTP-EQUIV="Expires" CONTENT="0">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">

and
either --> <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
or -->     <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache,
must-revalidate">

Thank you for your response. You say its not posible to do it with the
configuration of apache. neither sending headers to the clients?

Thanks again.

configure the clients not to cache pages! there's nothing you can do
about it with apache configuration.
