Hosting a directory of legacy static HTML files on Drupal My clients has a folder of static HTML files from 1999. I want to upload the folder to Drupal and then use an iframe to frame it in. I know it sounds awful but that's all he has the budget for. How can I get Drupal to ignore the entire directory and serve up the files "as is"? It is required that the files be hosted on the same domain.
As long as you're using the default rewrite rules you don't need to do anything.

Drupal's .htaccess file contains this:

# Pass all requests not referring directly to files in the filesystem to
# index.php. Clean URLs are handled in drupal_environment_initialize().
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^ index.php [L]


So requests for existing files won't be re-written, the file will just be served.
