Redirecting Txp-style Feed Url's to Feedburner in a Lighttpd/typo Setup

I reported earlier that I hadn’t yet gotten the old textpattern-style feed urls like jlaine.net/?rss=1 to work with the setup where all requests are reverse proxied to a lighttpd instance through apache. That has now changed. With the help of Ryan Schwartz from Textdrive I was able to combine rewriting and redirecting in the lighty config file so that all my feeds now point to feedburner. Here’s the setup:

$HTTP[“host”] =~ “mydomain.net” {
url.rewrite-once = ( “^/?rss=1(&section=blog)?” => “/xml/rss20/feed.xml”,
“^/?atom=1(&section=blog)?” => “/xml/rss20/feed.xml” )

$HTTP[“useragent”] !~ “FeedBurner” { url.redirect = ( “/xml/rss20/feed.xml” => “http://feeds.feedburner.com/mydomain” ) }

It might be possible to tackle it with just redirects, but I couldn’t get it understanding my regexps. In rewrite rules they work fine, though, so I don’t mind. Here we first rewrite all old school feed urls to the new typo-style, and then redirect to the FeedBurner feed unless the request comes from FeedBurner. Works a treat.
