Redirect to Subdir and preserve query string as is as part of filename

I have to redirect a domain to a subfolder using .htaccess. I have done this with

RewriteCond %{HTTP_HOST} ^(www\.)?domain\.de$ [NC]
RewriteRule !^domain\.de/ /domain.de%{REQUEST_URI} [L,NC]

This works for 90% of my site.

But I also have file reference like:

domain.de/templates/shaper_helix3/fonts/fontawesome-webfont.woff2%3Fv=4.3.0.html

The file exists in the filesystem with the filename: fontawesome-webfont.woff2?v=4.3.0.html (including query string)

These files are currently not found (404). If I manually remove the query string from the filename (e.g. resulting in fontawesome-webfont.woff2) I get a HTTP Code 200 (Found).

I have multiple files with said filename structure and can not "hardcode" them, because through updates and installation of additional modules via CMS I can not know, which files will exist in the future in the respective directories.

The reason for the files inlcuding a Query String / version in their names is cache busting.

How do I have to modify my rules, so that these files can also be found?

.htaccess mod-rewrite apache

With your shown samples/attempts, please try following htaccess rules. These rules are for internal rewrite ones.

Please make sure to clear your browser cache before testing your URLs.

RewriteEngine ON
RewriteRule ^(templates/shaper_helix3/fonts/fontawesome-webfont\.woff2)%3F(v=4\.3\.0\.html)/?$ $1?$2 [QSA,NC,L]

OR if it could be any file under templates/shaper_helix3/fonts/fontawesomefont/ then try following:

RewriteEngine ON
RewriteRule ^(templates/shaper_helix3/fonts/[^%]*)%3F(v=4\.3\.0\.html)/?$ $1?$2 [QSA,NC,L]
user_58665800 
RewriteCond %{HTTP_HOST} ^(www\.)?domain\.de$ [NC]
RewriteRule !^domain\.de/ /domain.de%{REQUEST_URI} [L,NC]

The "problem" here is that the REQUEST_URI server variable is already %-decoded so ends up rewriting a request for /fontawesome-webfont.woff2%3Fv=4.3.0.html to /domain.de/fontawesome-webfont.woff2?Fv=4.3.0.html (ie. a file fontawesome-webfont.woff2 with a query string of v=4.3.0.html, not a literal file called fontawesome-webfont.woff2?v=4.3.0.html). You need to maintain the %-encoding through the rewrite so %3F is rewritten to %3F, ie. /domain.de/fontawesome-webfont.woff2%3Fv=4.3.0.html (which is later decoded when the request is finally mapped to the filesystem), not ? (that delimits an actual query string).

You can do this by capturing the URL-path with a backreference (also %-decoded) but use the B flag that re-encodes the backreference before rewriting the request.

For example:

RewriteCond %{HTTP_HOST} ^(www\.)?domain\.de$ [NC]
RewriteCond %{REQUEST_URI} !^/domain\.de/ [NC]
RewriteRule (.*) domain.de/$1 [B,L]
