如果使用htaccess存在目录，则重定向到目录

Question

I have about 250 directories off of public_html that I want to move into /clients/. Since the original URL's eg mysite.com/bob are already used in the client's printed marketing materials, I need to keep them accessible. I'd like for when someone goes to mysite.com/bob (example), htaccess checks if mysite.com/agents/bob exists, then redirect to it, if it does. I've checked SO posts and came up with this so far, but am at a block trying to get it to work for any name scenario.

Options +FollowSymLinks
RewriteEngine On

ErrorDocument 404 /error_page.php

## check if path exists
## example: mysite.com/agents/bob

RewriteCond %{REQUEST_FILENAME} !-d

## if mysite.com/agents/bob exists, redirect mysite.com/bob 
## to mysite.com/agents/bob    

## The code below works - but just for bob. Want it to work for any name 
## e.g. mysite.com/tom, mysite.com/fred - to be redirected to 
## mysite.com/agents/tom, mysite.com/agents/fred respectively
## if mysite.com/agents/tom, mysite.com/agents/fred exist on the webserver

RewriteCond %{HTTP_HOST} ^mysite\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.mysite\.com$
RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteRule ^bob\/?$ "http\:\/\/mysite\.com\/agents\/bob" [R=301,L]

Answer 1

At your code , Replace last line :

RewriteRule ^(.+)\/?$ "http\:\/\/mysite\.com\/agents\/bob" [R=301,L]

With this :

RewriteCond %{REQUEST_URI} !/agents/
RewriteCond %{REQUEST_URI} !/error_page.php
RewriteRule ^(.+)\/?$     /agents/$1 [R=301,L]

So, the code above will redirect all request to /agents/ directory and exclude any request contains /agents/ to avoid looping then if the request is wrong error page will handle that and i excluded as well from this rule.

If you want to check first in /agents/ then in another location let me know to add another rules.

Clear browser cached the test it .

UPDATE :

Try this instead :

RewriteCond %{REQUEST_URI} !/bob/agents/
RewriteRule ^bob/(.+)\/?$     /agents/bob/$1 [R=301,L]

UPDATE 2

RewriteCond %{THE_REQUEST} !/agents/
RewriteCond %{DOCUMENT_ROOT}/agents%{REQUEST_URI} -f
RewriteRule ^(.*)$    /agents%{REQUEST_URI} [L,R=301]

The code above will check any request not contains /agents/ even to site.com/index then check /agents/ directory , if it is exist ok ,it will be redirect to /agents/ , otherwise will handle it as it is .

If you want to exclude index let me know
