 * You can get revisions by Query API so a Memento proxy that delivers raw MediaWiki code, could be created.


 * http://mementoproxy.lanl.gov/wiki/timegate/(URI) is exactly such a proxy.  Example link: http://mementoproxy.lanl.gov/wiki/timegate/http://en.wikipedia.org/wiki/Clock
 * Issues with by-proxy timegates versus native timegates:
 * Client needs to know where the proxy is, or MediaWiki needs to redirect to the proxy. Offsite redirection would allow for link hijacking by a misbehaving proxy.
 * The proxy will redirect back to the appropriate history page, but that page will not issue the X-Datetime-Validity or X-Archive-Interval headers. This makes it difficult for a client to detect that the page is a Memento.
 * The offsite redirection will take significantly longer to resolve, given the number of HTTP interactions:
 * Proxy: Client to MediaWiki, Client to Proxy, Proxy to MediaWiki, Client to MediaWiki
 * Native: Client to MediaWiki, Client to MediaWiki
