apache .htaccess url重写不能不加斜杠

Question

I am using Apache, trying to map different domain into different directory using .htaccess. Users access different directory when they type different domains. I use the rules below:

RewriteCond %{HTTP_HOST}   ^(www.)?mydomain.com$

RewriteCond %{REQUEST_URI}   !^/domaindir/

RewriteCond %{REQUEST_FILENAME}  !-f
RewriteCond %{REQUEST_FILENAME}  !-d

RewriteRule ^(.*)$   /domaindir/$1/ [L]

Everything works fine, except when I type domain.com/dir(without /), the browser will redirect to domain.com/domaindir/dir, I just want it stay in domain.com/dir. If I add / in the end, it will work fine.

Does anyone knows how to fix this?

Thank you anubhava,after using your code,I got another problem. when I typed mydomain.com,I will got 404,I don't know why it just access index.php instead of index.html,but if I typed mydomain.com/dir, it can fetch the index.html and works fine.the error log is below

[perdir D:/xampp/htdocs/] strip per-dir prefix: D:/xampp/htdocs/ -> 
[perdir D:/xampp/htdocs/] applying pattern '^((?!domaindir/).*?)/?$' to uri ''
[perdir D:/xampp/htdocs/] strip per-dir prefix: D:/xampp/htdocs/ -> 
[perdir D:/xampp/htdocs/] applying pattern '^((?!domaindir/).+?)/?$' to uri ''
[perdir D:/xampp/htdocs/] pass through D:/xampp/htdocs/
[perdir D:/xampp/htdocs/] strip per-dir prefix: D:/xampp/htdocs/index.php -> index.php
[perdir D:/xampp/htdocs/] applying pattern '^((?!domaindir/).*?)/?$' to uri 'index.php'

I still found stay in mydomain.com/dir will cause many files 404,how can I redirect to mydomain.com/dir/,thanks.

That is because of mod_dir adding a trailing slash for directories.

Try this code instead:

DirectorySlash off
RewriteEngine On

RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com$
RewriteCond %{REQUEST_FILENAME}  !-f
RewriteCond %{REQUEST_FILENAME}  !-d
RewriteRule ^((?!domaindir/).*)$ domaindir/$1 [L,NC]

# add a trailing slash now
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_URI} !-f
RewriteCond %{THE_REQUEST} \s/+(.*?)[^/][?\s]
RewriteRule [^/]$ %{REQUEST_URI}/ [L,R=301]
