regex simple replace help

Hey,
I'm trying to use regex for a simple redirection without succces. Only wants
to redirect '/dir/another/path/to/file.ext' into
'/dir/newone/another/path/to/file.ext'.
This is what I wrote:
^/dir\/another/(.*)$ -> /dir/newone/another/$1

Am I close?.. :p

Currently I'm getting internal server error.

Thank you!

Why are you only escaping one of the backslashes? In fact, since you're not
doing an s/// syntax, shouldn't that one not need to be escaped at all?

Well, I removed that slash and I still get 500 Internal Server Error.

Now my regex is '^/dir/another/(.*)$'.
Is there any simpler way to to this redirection?

What's the s/// syntax?

It's how you perform regex search-and-replace in perl, vim, a few irc bots I
know of, and I'm sure much more. s/foo/bar/ would replace all instances of
foo with bar. Backslashes have to be escaped when doing this, since they
are used to delimit the terms.

I'm not sure exactly how Cherokee handles regexp, though, so I can't say
anything about its behavior in regard to those kind of special cases.

What do you see in the logs?
