Lightning speed WordPress with Lighttpd and Supercache, part II
Posted by Giovanni Intini | Filed under Lua, Wordpress, lighttpd
There was an error in the code I wrote for my previous post about lighttpd and wp-supercache. If you kept GZip disabled in you wp-supercache configuration, and your browser sent an Accepts gzip header, lightpress would serve the dynamic page (instead of the cached html page).
I did some refactoring and testing, and here’s the current version of rewrite.lua. This one will serve the correct gzipped or text content, while solving another bug with urls ending in ”/”:
function serve_html(cached_page) if (lighty.stat(cached_page)) then lighty.env["physical.path"] = cached_page print("Serving cached page: " .. cached_page) return true else return false end end function serve_gzip(cached_page) if (lighty.stat(cached_page .. ".gz")) then lighty.header["Content-Encoding"] = "gzip" lighty.header["Content-Type"] = "" lighty.env["physical.path"] = cached_page .. ".gz" print("Serving gzipped page: " .. cached_page .. ".gz") return true else return false end end 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" cached_page = string.gsub(cached_page, "//", "/") if (string.find(accept_encoding, "gzip")) then if not serve_gzip(cached_page) then serve_html(cached_page) end else serve_html(cached_page) end end end
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.
