.htaccess从带有结尾/文件夹的URL中删除扩展名

Question

I am using the current code to remove .shtml from my URLs for a project of mine:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ $1.shtml
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.shtml
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=301,L]

It is working perfectly till I make more than one subfolder, such as /folder1/folder2/ , then it can not find the folder 2 argument. I am not even sure where to go from here to make it work (I don't have much experience at using .htaccess )

Answer 1

why not just replace these two lines:

RewriteRule ^([^/]+)/$ $1.shtml
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.shtml

with

RewriteCond %{DOCUMENT_ROOT}/$1.shtml -f
RewriteRule ^(.*)/$ /$1.shtml [L]
