RewriteRule won't match if trailing slash present, throws nginx 404

With this .htaccess...

RewriteEngine on
RewriteRule ^foo$ foo.php
RewriteRule ^foo/$ foo.php

...I get the following behavior, when I request

/foo — works, I get foo.php
/foo/ — fails unexpectedly with a bare 404 from nginx
/foobar — fails, as expected, but with a pretty 404 ErrorDoc from nginx

Note: there is no folder foo present.

Am I missing something or is this the hosting provider's fault, like a nginx proxy misconfiguration? On a different apache, this setup works as expected.
(I'm trying to drill down why WordPress's (default-ish) .htaccess doesn't work.)

If you are getting a 404 response from an Nginx server then this evidently has nothing to do with your `.htaccess` file (which obviously only applies to Apache). Are you sure you're using Apache at all?!

@MrWhite looks like you're right... two "websites" in the same account run on apache and nginx, apparently. I just assumed it was a nginx (reverse?) proxy in front of apache because mod_rewrite *half* works...

Yes, I too would have assumed an Nginx proxy in front of Apache if it wasn't for your last example... "`/foobar` — fails, as expected, but with a pretty 404 ErrorDoc from nginx". But then again, if mod_rewrite "half works" then maybe this is just a proxy. I assume then that `foo.php` is served from Apache? If you remove `.htaccess` altogether and request `/foo`, is `/foo.php` still served? (This is could indicate that MultiViews is enabled in the server config, so `.htaccess` may not be doing what you think it's doing?)

@MrWhite without `.htaccess` `/foo.php` is not served. Thank you for your input, I've contacted support now, because this looks more and more like misconfiguration on their part.

E-mailed support, they fixed it.
From what phpinfo tells me, $_SERVER['SERVER_SOFTWARE'] changed from nginx to Apache...
For future searches: this was on the web host provider checkdomain.de.

TH: RewriteRule จะไม่ตรงกันหากมีเครื่องหมายสแลชต่อท้าย โยน nginx 404

RO: RewriteRule nu se va potrivi dacă este prezentă o bară oblică finală, aruncă nginx 404

RU: RewriteRule не будет соответствовать, если присутствует косая черта в конце, выдает nginx 404

VI: RewriteRule sẽ không khớp nếu xuất hiện dấu gạch chéo, ném nginx 404

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
