Token based URI access module for Apache
mod_auth_token allows you to generate URIS for a determined time window, you can also limit them by IP. This is very useful to handle file downloads, as generated URIS can't be hot-linked (after it expires), also it allows you to protect very large files that can't be piped trough a script languages due to memory limitation.
