mod_rewrite help - GET request

I'm having trouble w开发者_JS百科ith what should be a simple mod_rewrite. I want to convert the following URL:

http://example.com/c/c0001

to

http://example.com/c/index.html?c=c0001

I've tried for the life of me and cannot get the rewrite to work. I know htaccess is being read as my trial attempts are yielding different results, but nothing to get the result I want. Some examples of what I've tried:

Options +FollowSymlinks
RewriteEngine on

#RewriteRule (.*) index.html?c=$1 [L]
#RewriteRule ^([^/\.]+)$ index.html?c=$1
RewriteRule ([^/\.]+) index.html?c=$1 [L]

and many other iterations. Can anyone help? Thanks!

Try the following:

RewriteEngine on

RewriteRule c/(.+) index.html?c=$1 [L]

I would encourage you to be more specific though, for example if c is always in the format c#### and optionally allowing for the trailing slash.

RewriteEngine on

RewriteRule c/(c\d+)/? index.html?c=$1 [L]
