Look first for local copy

This allows you to replace downloaded files on the fly.

WebMask searches in this directory for any file requested from it. If it finds it, then it returns the local file from the directory, rather than making a request from the network.

Only the filename after the final / of the requested URL is searched for; the rest of the path is ignored.

This option is useful

• To point to an already-downloaded version of a page when using active setup programs, avoiding you having to download again.
• To point to a hacked Java .class file, when there's no explicit text that can be altered in the HTML for the page, or when the security on the file won't allow it to be run from any URL other than the original.
• As a first-level approximation to replacing a URL with an arbitrary file, rather than a blank image.
