Re: [Phplib-users] How to disable browser caching

[Mikhail A. <ma...@lb...>]

To resolve this problem, we've compiled apache with mod_headers enabled:
(--activate-module=src/modules/standard/mod_headers.c),
and added something along the following lines into httpd.conf:

<Directory />
    Options FollowSymLinks
    AllowOverride None
    Header append Pragma "no-cache"
    Header append Cache-Control "no-cache, must-revalidate, max_age=0"
    Header append Expires "0"
</Directory>

This solved the problem of stale pages being displayed in Netscape (and
BTW, it wasn't simply that you couldn't see the HTML source of
POST-created documents, but you couldn't print those documents -- the
printer returned a page with the same old "document has expired" message.

To be honest, I am not completely sure why this way of sending the
no-cache pragma header is better than the way PHPLIB does it when you set
allowcache=no , but for some reason it seemed that the latter was entirely
ignored by Netscape 4.x  Any ideas on this ?
