为什么我的rewriterule从替换字符串而不是uri中捕获部分

Given this url:

http://test.com/myfile/product/1

and the following RewriteRule:

RewriteRule ([^/.]+)/?(.*) app/$1.php?$2

I would expect the url to become:

http://test.com/app/myfile.php?product/1

and it does when I use an online htaccess tester. But on my local dev environment I get this:

The requested URL /app/app.php was not found on this server.

Why? This can't be right, right? I suspect it is a bug caused by my setup (docker containers and dinghy-http-proxy) but since I am new to this rewriting I am not sure.

Try this:

RewriteRule ^([^/.]+)/?(.*) app/$1.php?$2

The problem is that the regex can match anywhere in the path string, and since the / is optional the result is unlikely to be what you want.

Also, make sure that you don't have multiple rewrite rules which apply, they will all get processed by default!
