regex help

[haku]

I've been trying to write a regex expression that matches any image in the domain:

 

static.exa-mple.com (the hyphen is deliberate).

 

The images may be at the root or in subfolders. I have this:

 

 

<FilesMatch "^http://static(.*).(ico|jpg|jpeg|png|gif)$">

Header set Expires "Sun, 30 Nov 2008 20:00:00 GMT"

 

</FilesMatch>

 

And it doesn't work. I've tried every variation I can think of with no success. Can anyone give me a hand? Thanks.

It's just local files.

 

 

Unfortunately I can't remember which tag lets you use the Request_URI environmental variable.

 

IfSetEnv or something.
