.htaccess same url with or without /

Question

Howdy Guys, I am doing a painful rewrite of many urls on a website I am currently working on, but I have noticed a small problem:

RewriteRule ^domains/transfer$ ./cart.php?gid=11 [L,NC]

This line with navigate if I go to:

http://my-site/domains/transfer

But it won't work with a trailing /:

http://my-site/domains/transfer/

Is there a way I can change the RewriteCode to take either argument and go to the same page. It seems wasteful to have the same line twice to include a '/'

Any help would be appreciated.

Cheers

Answer 1

Change the line to this:

RewriteRule ^domains/transfer/?$ ./cart.php?gid=11 [L,NC]

The magic is here: /? and that allows for the preceding character, in this case the slash (/), to be optional.

If you want something to come after the transfer, then remove the dollar sign ($) which marks the end of the allowable matching.

Answer 2

I would recommend you to allow just one URL form, the one with or without the trailing slash, and redirect if malformed:

# remove trailing slash
RewriteRule (.*)/$ /$1 [L,R=301]

# add trailing slash
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .*[^/]$ /$0/ [L,R=301]
