I want to simulate virtual hosts by .htaccess, so I want to rewrite hostname to subfolder. It works, but on some URLs it don't rewrite but redirects.
This is my .htacess file:
RewriteEngine on
RewriteBase /
# Rewrite from subdomains to subfolders with builds
RewriteCond %{HTTP_HOST} ^(.*)\.(.*)\.ci\.example\.com$
RewriteCond %{REQUEST_URI} !^/builds/
RewriteCond %{REQUEST_URI} !^/robots.txt
RewriteRule ^(.*)$ /builds/%2/%1/$1 [PT]
# Example project
RewriteCond %{HTTP_HOST} ^old\.domain\.com$ [NC,OR]
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
# Rewrite production to master subfolder
RewriteCond %{HTTP_HOST} ^www\.example\.com$
RewriteCond %{REQUEST_URI} !^/builds/
RewriteRule ^(.*)$ builds/example-project/master/$1 [PT]
If I access for example http://example.com/ it will rewrites correctly to /builds/sum/folder.
If http://example.com/page.html it will rewrites to /builds/sum/folder/page.html.
But if I access http://example.com/folder it will not rewrites but 301 redirects to /builds/sum/folder/folder (and there it loads index.html).
Why it rewrites always but redirects if target path is not existing file, but folder with index.html? (I want to rewrite it all, so URL in browser will not change.)
EDIT: For better understanding what happens:
