+# Customize nginx config
+
+## Add custom config for a virtualhost config
+
+Add a config snippet to `data/nginx/vhost.d/<vhost-name>`, it will be included in the respective vhost config automatically.
+
+For example to redirect all requests to `/apps.*/text` to a `vite serve` process on the docker host, add the following to `data/nginx/vhost.d/nextcloud.local`:
+
+```
+location ~* ^/apps.*/text/ {
+    rewrite ^/apps.*/text/(.*) /$1 break;
+    proxy_pass http://host.docker.internal:5173;
+    # fallback to nextcloud server if vite serve doesn't answer
+    error_page 502 = @fallback;
+}
+location @fallback {
+    proxy_pass http://nextcloud.local;
+}
+```
