**Type:** STRING  
**Access:** read-only

**Available in:** pass, miss, fetch

The file extension portion of `bereq.url`. If
multiple file extensions are present, only the last extension is used. For
example, given the path `/foo.bar.txt`,
`bereq.url.ext` would be `txt`. If no
file extension is present, the value will be an empty string.

This variable is updated any time `bereq.url` is
set.
