Comment (by sivel):

 Replying to [comment:10 g1smd]:
 > What is the mechanism for a URL request serviced by "WP_rewrite"? You're
 saying those are URL requests that are rewritten to the index.php script
 and then handled from there?
 >
 > Just to be clear, you are saying that a request for /someimage.jpg (for
 example) is rewritten to the index.php script and the index.php script
 sends an image back?

 In the only public example I have to show currently,
 http://paste.sivel.net/embed/24.js is not a real file.  It is generated
 similar to the way a post is.  The request comes in, the file doesn't
 exist so it is sent to index.php and processed.  WP_Rewrite has a regex
 pattern looking for this type of URL, and in the end gets the request to a
 custom template file within my theme, based off of internal query vars the
 same way that a post is rendered.  In this case I send the correct HTTP
 headers for a JS file, and output some JS.

 I have other applications built off of WP which are not publicly
 accessible which generate documents, css and images in this manner.

 So basically yes, requests to non-existent files such as image files,
 PDFs, JS are rewritten to index.php via the current .htaccess, which then
 processes the request using custom rewrite rules via WP_Rewrite, and
 delivers back the expected type of content.

 Adding rewrite rules to exclude images, js, css, etc would not permit this
 to work.
