Shaijee which is why I suggested advanced features for Enhance.
I'm sorry but this is actually not the "advanced feature". I've tested, and searched for all available detailed tests, most kinds of Webserver stacks in the past a few years. Apache with Ngnix doing reverse proxy was not as efficient as Nginx alone, for WordPress. George (eva2000), the developer of Centminmod, has done a lot of such thorough tests in the past. You may want to check. If the usage of .htaccess is the main point, then OLS would already surpass Apache+Nginx.
Another thing I may want you to notice is, there are always open source projects or self-developed-managed projects on the web server part coming out every now and then. They want to compete with the big brands, so they usually try to use the hottest and most promising technologies at the moment. As far as I know, before Plesk has implemented Apache+Nginx, there were a lot of active Webserver stacks projects using this. But recent years, especially since 2020, I've seen a lot less of them. Even Nginx+Vanish is more popular now.
So no, please don't consider Apache+Nginx to be an advanced feature. I'd rather Enhance team to spend more time on making the configs of OLS permanent, which would be a very unique competing advantage on the market.
Anyway, I could be wrong. That's just my 2 cents.
