RewriteBase - 引导我到同一个目录?

I have built myself a small MVC with following htaccess

RewriteEngine On

RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+)$ index.php?controller=$1 [QSA,L]

when I now click on a link http://example.com/mycontroller/ I get to the controller mycontroller.. everything works fine here.

but inside http://example.com/mycontroller/ I have further links i.e. http://example.com/mycontroller/edit/1 which lead me to http://example.com/mycontroller/mycontroller/edit/1 (?)

how can that be? how can I fix this?

How do the links in your HTML look like?

<a href="/mycontroller/edit/1" ... or <a href="mycontroller/edit/1" ... ?

The latter is relative to the current path, and when you're already at /mycontroller/, it will expand to /mycontroller/mycontroller/edit/1

To solve this you need to make your links server-relative (i.e. begin with a /)
