How to use $RDIR to redirect to a local file

[Guest]

I want to redirect request for http://www.hyperigo.com/favicon.ico to a local file C:\favicon\hyperigo.ico

I tried a URL filter like this:

Code:

[HTTP headers]
In = FALSE
Out = TRUE
Key = "URL: Hyperigo icon (out) [wpw]"
URL = "*hyperigo.com/favicon.ico$RDIR(http://file//C:/favicon/hyperigo.ico)"

But proxo failed to load the file and give an error like this

Check that the name is correct. If so, the site may have changed or may no longer exist.

What's the correct way to write the path to a local file ?
