The Mobile Web Proxy is a (CGI) tool to make more Web pages available from some mobile devices (cell phone Web browsers, etc.). It employs tag cleaning and paging so that Web pages it can access have far greater chances of being rendered on devices that cannot display overly large or complex pages. It is simple, but it seems to substantially extend the portion of the Web available from devices that otherwise display messages like "413: Page cannot be displayed."
