Remote Address Rewrite

[tlaverdure]

I use this rewrite in .htaccess to rewrite missing files like images. Is this possible with Caddy?

RewriteBase /wp-content/uploads/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*) http://example.com.com/wp-content/uploads/$1 [L,P]

How does an internal rewrite work if the image is on a different site?

You can use redir though!

Thanks for the reply. Was just basing this off what I used in my .htaccess.

So with redir can I redirect all files under a path that aren’t found locally to a remote file?

Welcome by the way!

No, redir simply maps a path to a redirect URL. (0.9 adds an if keyword you can use, but I’m not sure it supports whether files exist. @abiosoft could confirm, maybe get inspired… ;))

Thanks! Been using Caddy along with Laravel Valet. Works great!

It doesn’t look like redir will work in this case. If rewrite allowed external destinations I would be able to pull this off. This would be useful when working on a website locally and you don’t want to pull GBs of images. Or if you are migrating a website to a different location and need time to move uploads from one location to another without impacting user experience with missing images.

On another note, think I found a working solution using without on proxy. (Which by the way has a missing description in the docs).

rewrite /wp-content/uploads/ {
    ext .jpg
    to  {path} {path}/ /rewrite/{uri}
}

proxy /rewrite/ example.com {
    without /rewrite
}

That’s clever!

And it is described in the docs, as prefix is a variable/placeholder value, which has a description of what the actual value should be:

prefix is a URL prefix to trim before proxying the request upstream. A request to /api/foo without /api, for example, will result in a proxy request to /foo.

[tlaverdure]

Gotcha. Thanks for the help!

I am already considering depreciating ext for rewrite. Looks like it’s still useful.

The workaround would be to use regex or if match.
