Lighttpd and WP-Supercache? Now you can!

Update: there are some bugs with this code. You can find the newest (and best) version here
It’s often said that if you can’t find something in Google it doesn’t exist, and when I couldn’t find a way to serve WP-Supercached pages via Lighttpd I was pretty sure no one had ever published on the net a solution to my problem.
Nice permalinks were easy to fix, thanks to this tutorial, but cache was a no-go: the lighttpd wiki and the wordpress forums had no info, so I had to cook a solution for myself.
It was easier than I thought though:
-- rewrite.lua, in your WP_ROOT attr = lighty.stat(lighty.env["physical.path"]) if (not attr) then lighty.env["uri.path"] = "/index.php" lighty.env["physical.rel-path"] = lighty.env["uri.path"] lighty.env["physical.path"] = lighty.env["physical.doc-root"] .. lighty.env["physical.rel-path"] query_condition = not (lighty.env["uri.query"] and string.find(lighty.env["uri.query"], ".*s=.*")) user_cookie = lighty.request["Cookie"] or "no_cookie_here" cookie_condition = not (string.find(user_cookie, ".*comment_author.*") or string.find(user_cookie, ".*wordpress.*") or string.find(user_cookie, ".*wp-postpass_.*")) if (query_condition and cookie_condition) then accept_encoding = lighty.request["Accept-Encoding"] or "no_acceptance" cached_page = lighty.env["physical.doc-root"] .. "/wp-content/cache/supercache/" .. lighty.request["Host"] .. lighty.env["request.uri"] .. "/index.html" if (string.find(accept_encoding, "gzip")) then if (lighty.stat(cached_page .. ".gz")) then lighty.header["Content-Encoding"] = "gzip" lighty.header["Content-Type"] = "" lighty.env["physical.path"] = cached_page end else if (lighty.stat(cached_page)) then lighty.env["physical.path"] = cached_page end end end end
This rewrite.lua will serve compressed cached pages to those who accept gzip and plain html to those who prefer not to get gzip, while retaining the nice permalinks.
