Weird 404 not found errors

[Edi Duluman]

Hello guys ! I have a client who's running Smarty just fine on one of his old servers.
He decided to do a move to test the perfomance on the new server and I'm having this annoying problem which I can't really figure out how to solve.

Here you have two requests, first one ends up in 404 Not Found and second one works fine.

1. http://nakenpraten.com/external_c/dp/%%10/103/10379A4F%%form_QuickSearch.js
2. http://nakenpraten.com/external_c/dp/%%CA/CAD/CADB2AD9%%menu-line-bottom.style.css

I don't understand what's the difference between these two ?

The files exist at the following paths:

1. /external_c/dp/%25%2510/103/10379A4F%25%25form_QuickSearch.js
2. /external_c/dp/%%CA/CAD/CADB2AD9%%menu-line-bottom.style.css

They work just fine on the old server... and I'm really struggling to understand what's different here.
Do you have any idea ?

Sometimes I get some errors from nginx access like this:

1253#0: *1781 open() "/var/www/vhosts/nakenpraten.com/httpdocs/external_c/dp/%DE/DE6/DE65EBD5%form_SignUp.js" failed (2: No such file or directory)

I don't understand why nginx sees %25%25 ( originally %% ) as only one %.

Print of the logs:

I havel literally no idea..

I have found out that if I disable Smart static files processing for the domains that have trouble with this in Apache & Nginx Settings after few minutes, if you refresh couple of times, the errors dissapear. It's very strange. Before finding the workaround, there were files that sometimes were loading, sometimes they were returning a 404. Don't understand why.
