Apache，在404上的mod_rewrite中，检查文件系统中的文件

Question

At the moment, I'm migrating a site, and due to time constraints, we've migrated most to a CMS (Drupal), but still have some flat HTML sub sites that need to get served outside of this.

Now, config wise, I've setup Apache to pass requests for files that do exist and get served directly, rather than sending the request to the CMS:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [L]

As we get more time, the team would like to slowly import the pages we've left out of the CMS from the file system, but we don't have the ability to easily delete those additional files from the file system once we've imported them to Drupal (service provider deploy method unfortunately - so not changable).

We're using the same URLs as the old site (maintaining legacy links/addresses and all that), so once we've recreated the page in the CMS, the above rewrite rule is still going to serve the page from the file system.

What I would like to do to get around this, is route all requests through Drupal using mod_rewrite, then if Drupal throws a 404, attempt to pull the URL from the file system, rather than what we have currently, which is if the file exists, serve that automatically. From a day or so of searching, I can't find a way of achieving this, can't even really find a lot of people having run into this issue before actually.

Naturally, if I had full control over our environment, it would be easy to just delete the underlying files once they've been migrated, but that's not so simple in this case.

I also understand doing this will incur an overhead, but given this will only apply for a small part of the site, I'll be evaluating any solutions to see whether it is an acceptable compromise.

Any thoughts?

Answer 1

Can you add a RewriteCond that will kick in before what you have there that checks for specific paths and sends them directly to index.php?

Something like

RewriteRule ^/some/path/to/file.html$ index.php [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [L]

It might get kind of unwieldy if you have a lot of disparate paths, it would be nicer if your existing static files had a nice regexable pattern
