Drupal alias your file paths using htaccess

Posted by:

Clients often ask for clean urls in file names because they want to publish them in magazines so they want urls as clean as possible. H

Here is how to do this using mod_rewrite rules in htaccess:

In your .htaccess file of your drupal root folder you add following line.
For example :
All http://yourdrupal/pdf/whatever.whatever will be redirected to http://yourdrupal/sites/yourdrupal/files/private/whatever.whatever

  RewriteRule ^pdf/(.*)$ /sites/yourdrupal/files/private/$1 [L,QSA]

For more info on apache mod_rewrite rewrite rules: http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html#rewriterule and http://httpd.apache.org/docs/2.0/misc/rewriteguide.html

To output logging you should put this in your virtual host directive:

RewriteLog /rewrite.log
RewriteLogLevel 9

This will give you a clear view on how apache is rewriting.

To not interfere with drupal rewriting you should put an extra condition in the drupal rewriting. (Taken from .htaccess)

For example

  RewriteRule ^(.*)$ /sites/default/files/$1 [L]
  #the [L] will tell apache to stop executing other rewrite rules
  # Rewrite URLs of the form 'x' to the form 'index.php?q=x'.
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_URI} !=/favicon.ico
  RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]

Could you give more details on the third example? For example, which portions should be customized to meet individual site needs?

Well the [L] makes apache stop doing the other rewrite rules if it finds a match.

What we want to achieve was to rewrite paths comming in from /DATASERVICE/WIKI/somefile.pdf to /sites/default/files/somefile.pdf

If this match should be made we dont want apache to try and excute yet another rewrite rule, in drupals case the default rewrite rule where you rewrite to /index?q=...
