a newbie question regarding regex in nginx conf

[Zhang Yining]

Hi list,

I have a question regarding regex in nginx conf, and believe it must
have been brought up before, yet after googling for it, I could not find
an answer.

Specifically, is it possible to use curly braces in nginx conf?

For example, for some url like: /photos/123456

I would want to rewrite it to: /path/to/photos/12/1234/123456.png

in apache's conf rewrite rule, I could use something like:

[0-9]{2}[0-9]{2}[0-9]{2}  /path/to/photos/$1/$1$2/$1$2$3.png

But it seems curly braces are reserved for nginx conf file's own use,
and not recognized by the regex processing.

So is there any way to use curly braces in regex? If so, could some one
kind enough to provide a link or short explanation of how to do it?

Thanks in advance,

Yining
