With thanks to nordisch.org darix and MrWerewolf
I've been wrestling with a planned migration to lighttpd for a few days now, on the whole I've found it much easier than apache to configure something that works, and for the most part have done it much faster than the last time I had to configure Apache from scratch. The big sticking point was Drupal sites with an embedded gallery2.
I think I've cracked it using some rewrites and the magnet approach, I'm not sure if I've got the lua script right, actually, i'm pretty sure it's not matching the case I had to code some extra re-writes for. If anyone can spot where I've gone wrong I'll love them forever (or at least send them coffee).
Update: After feeding myself more coffee, I fixed it, see #typo below.
drupal.lua
-- little helper function
function file_exists(path)
local attr = lighty.stat(path)
if (attr) then
return true
else
return false
end
end
function removePrefix(str, prefix)
return str:sub(1,#prefix+1) == prefix.."/" and str:sub(#prefix+2)
end
-- prefix without the trailing slash
local prefix = ''
-- the magic ;)
if (not file_exists(lighty.env["physical.path"])) then
-- file still missing. pass it to the fastcgi backend
request_uri = removePrefix(lighty.env["uri.path"], prefix)
-- rules for drupal
if request_uri then
local uriquery = lighty.env["uri.query"] or ""
if string.find(request_uri, "v/") == 1 then
lighty.env["uri.path"] = prefix .. "/index.php"
if #request_uri > 2 then
g2_path = string.sub(request_uri, 3)
else g2_path = ""
end
lighty.env["uri.query"] = uriquery .. (uriquery ~= "" and "&" or "") .. "q=gallery&g2_path=" .. g2_path
else lighty.env["uri.path"] = prefix .. "/index.php"
# end # typo
lighty.env["uri.query"] = uriquery .. (uriquery ~= "" and "&" or "") .. "q=" .. request_uri
end # fix for typo
lighty.env["physical.rel-path"] = lighty.env["uri.path"]
lighty.env["request.orig-uri"] = lighty.env["request.uri"]
lighty.env["physical.path"] = lighty.env["physical.doc-root"] .. lighty.env["physical.rel-path"]
end
end
-- fallthrough will put it back into the lighty request loop
-- that means we get the 304 handling for free. ;)

Cool
Hey I'm glad my code helped you. I spent a few nights figuring it out myself. I don't think I posted my code with that typo though. I'm very sorry if that's the case.
