rewriting/redirecting all external links to a new link - I'm a newbie

rewriting/redirecting all external links to my domain with.php=#*$!x

[montreal06]

Hello,

I am trying to rewrite all my external links on my site into a new URL.

For example:

external link: http://www.example.com/home/news.php?id=31155

should be

http://www.example.com/bt2/wp-content/plugins/topbar-plugin/topbar.php?url=http%3A%2F%2Fwww.asianewsnet.net%2Fhome%2Fnews.php%3Fid%3D31155

All of the external links will have the format http://www.example.com/bt2/wp-content/plugins/topbar-plugin/topbar.php?url=examplexx

Note: I want to make an exception that www.cnn.com be excluded from a rewrite and redirect rule

Thanks,
Mike

I tried looking for this using keywords external redirect or external rewrite, but I did not get the results I wanted

Well, you don't always get the results you want. But if you try sometimes you just might find you get the results you need.

You can constrain the search to /apache/ to narrow it down. You don't want an external anything; "external rewrite" in particular is a contradiction in terms unless you're messing about with proxies. (My advice: don't.) Sometimes Apache says "internal redirect" where we say "rewrite" alone.

Why does the query string need to contain the complete URL? Seems like it would be more efficient to make your php page look it up when the request gets there, instead of shoving it all into htaccess. There's obviously no way to make htaccess generate text from numbers, so it has to be either looked up or explicitly written out.
