Make Folders in Apache Case Insensitive using .htaccess - .htaccess

Question

I need to make accessing directories on my server case insensitive.
How do I do that using htaccess?

Answer 1

You have to install and enable the mod_speling module in apache and set the CheckCaseOnly Directive to On in your .htaccess
CheckCaseOnly On

Answer 2

If you want requested URLs to be valid whether uppercase or lowercase letters are used, use mod_speling to make URLs case-insensitive. Write the following code in .htaccess file:
CheckSpelling On

Answer 3

This is what I used because my hosting is shared and does not include the mod_spelling module but does support .htaccess, but this only works for one folder:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^student-government/$ http://www.tombarrasso.com/Student-Government/ [R=302,NC,L]
The folder to redirect to can be any case, so you could use lower-case folders and redirect all variations of spelling there.
I suppose it could be adapted with a little bit of REGEX to work for all folders rather than just one. This worked for me on Apache 2.2.14 (Unix).

Answer 4

Solution-1: To make case-insensitive directory and files names with respect to the requested URL we can add the following two lines to the app's .htaccess file:
<IfModule mod_speling.c>
#Once enabled, mod_speling redirects misspelled requests to any nearest matching resources. Uses a bit of memory, but can be useful if you've been changing URIs or have lots of similarly named URIs:
CheckSpelling On
CheckCaseOnly on
</IfModule>
Solution-2:
Again if we want just a few predefined directories to go to specific directories, then apply the below lines instead:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^my-dir/old-dir-1/$ /my-dir/new-dir-1/ [R=301,L,NE]
RewriteRule ^my-dir/old-dir-2/$ /my-dir/new-dir-2/ [R=301,L,NE]
RewriteRule ^my-dir/old-dir-3/$ /my-dir/new-dir-3/ [R=301,L,NE]
# For any case insensitive directories we can try adding NO-CASE (NC)
RewriteRule ^My-Old-Dir/$ /my-new-dir/ [R=301,L,NC]
</IfModule>
