You can use the Google Search app. Go to apps and choose Translate. Paste (or enter) the URL into to the text box (I just copied one from the Safari URL box). Choose the language. Tap the Search icon.
In my tests, the links that worked at all, the pages stayed translated as long as you don't kill the extra translate bar at the top of the page. Occasionally hitting a link will result in a popup menu asking if you want the page in English, the current feed, or want to offer a better translation.
Other than that, it worked well enough. Well I think it did. Since I don't read Esperanto (the language I tested) I've no idea how the actual translations were; but the pages were translated.
