---------------------------------------
Yea, we can do the query [after the page has
loaded|http://stackoverflow.com/questions/807878/javascript-that-executes-after-page-load],
and then add the icon/link to the DOM if we get a non-200 response..
> Switch version button may link to invalid url when we add/delete pages in
> latest version

>
> Current switch button in right-up corner has bugs in the following two
> situations:
> 1. if we add a new versioned page which only exists in the latest version but
> not previous version, when we click the switch button, it goes to an invalid
> url.
> e.g. we have page
> {code}
> http://samza.incubator.apache.org/learn/documentation/latest/new.html
> {code}
> the switch button in this page will link to
> {code}
> http://samza.incubator.apache.org/learn/documentation/0.7.0/new.html
> {code}
> which actually does not exist.
> 2. on the other hand, if we delete a versioned page in latest version,
> whenever we click the switch button in old page, it links to an invalid link
> too.
> e.g. we have old page
> {code}
> http://samza.incubator.apache.org/learn/documentation/0.7.0/old.html
> {code}
> The switch button in this page actually links to
> {code}
> http://samza.incubator.apache.org/learn/documentation/latest/old.html
> {code}
> However, obviously, the link is invalid because we already delete this page.
