I just have just found this article, that describes this technique: http://apachetoday.com/mailprint.php3?action=pv&ltsn=2000-06-14-002-01-PS#SetEnvIf Thank you all for your help. :-)) S

    Order Allow,Deny
    Allow from env=local_ref
</FilesMatch> This will stop and direct requests to files as the env var will not be set. I've used it on my setup and it's fine. As noted above this will only work with apache > 1.3.12 If you get it working could you forward it to the php list I can't get there through this a/c HTH M@ --- Stefen Lars <stefenlars@hotmail.com> wrote: > Hello all I have just implemented a mySQL authorization: each html and php page checks to see whether a user is logged in by checking a cookie in the user browser. The user can log out and edit her profile (including password). If a page is called without the user being logged in, he is presented with a log in form. This works very well. There is an SSL connection to the server. Only a hash value of the password is stored in the database. However, if I directly request a graphic (or a ZIP file etc) from the site, by entering: https://www.myserver.com/photo.jpg for example, I can download that file without being logged in (naturally). In the particular *intranet* project that I am working on, this is particularly undesirable, as only personnel at the company’s four locations may have access to the intranet. And there certainly will be a lot of ‘confidential’ ZIP and graphic files placed on the server. I do realize that if I were to place a .htaccess file in the root of the intranet server, I could prevent the above from happening, but then I loose the advantage of having the users profile in a database, where a user can easily change her password. Allowing a web user to edit a password in the .htaccess file poses more problems than it solves, especially as it certainly could occur that more than one persons wants to edit his password simultaneously. Could anyone suggest a method to allow a user to easily edit his password, but at the same time, not allow direct access to specific non-PHP files on the intranet server? Perhaps one method would be to restrict access to the company’s four gateway servers (IP addresses). However, I feel this is not to secure, and these IPs could be spoofed (and this does not really solve the problem). Any enlightenment on this subject would be well received.
