Apache .htaccess not working
Posted on 2012-12-26
Hello, I created a htaccess and passed it at the root of the html directory. I even set it so that apache is the owner of the file. However, I am still able to hotlink to my image or pdf file. What could be the problem? Please see my htaccess file below.
Thanks for your assistance.
#prevent viewing of .htaccess file
<Files .htaccess>
order allow,deny
deny from all
</Files>
#prevent directory listing
IndexIgnore *
#custom error message
ErrorDocument 401 /custom-error/401.php
ErrorDocument 403 /custom-error/403.php
ErrorDocument 404 /custom-error/404.php
ErrorDocument 500 /custom-error/500.php
#prevent hotlinking to images (gif, png, jpg), documents (csv, pdf, xls, xlsx) and web files (javascript: js, css)
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^https://(www\.)?mydomain.com/.*$ [NC]

You may get a good answer on the Apache front, but in case you do not, or you want a little stronger way to discourage hotlinking, this article will show how to watermark hotlinked image files. If the watermark is not enough for you, you could change the script a very little bit and render a picture of something else that would discourage further hotlinking...

If you have root access, put the above block in the httpd.conf, as Apache will only have to parse and compile the rules once, at server start-up, rather than for every browser request received by Apache.
As to why it dosen't work, loose the first Http_referer condition, as that's allowing BLANK referer strings.

abolinhas -- i tried that and the code look the same to me.
arober11 - i don't think it is i the http_referer condition. it is recommending to have the blank refere string and i do want that as part of the condition
ray_paseur - that is a good idea if images and other files aren't changing as often as it is here.
I am still hoping to use htaccess so that I have control over security instead of having to rely on system admin because they are the only one who can configure the httpd.conf file.
Does anyone else see or know why my code might not be working??

If you want to see what's going on, have the admin temporarily paste the following into you httpd.conf and restart Apache:
RewriteLog /tmp/tmp_apace_rewrite.log

arober11 - I have the admin perform the modification to the httpd.conf and when I viewed the log file, I get the following:
(2) init rewrite engine with requested uri /
(3) applying pattern '^(/htdocs/.*)' to uri '/'
(3) applying pattern '.*' to uri '/'
(4) RewriteCond: input='GET' pattern='^(TRACE|TRACK)' => not-matched
(1) pass through /
(3) [perdir /var/www/html/] strip per-dir prefix: /var/www/html/ ->
(3) [perdir /var/www/html/] applying pattern '\.(gif|png|jpg|csv|pdf|xl
(1) [perdir /var/www/html/] pass through /var/www/html
Does the log indicates what the problem might be?
