In response to my questions about using Lua and
Lighttpd to serve up static blosxom pages, Tomas Carnecky sent me an email
with a better way to check for an empty query string within Lua, using "if
next(get) then return 1 end". Here's my new power-magnet.cml
-- if query string is empty and static file exists, serve static file
dr = request["DOCUMENT_ROOT"]
-- local f=assert(io.open(dr.."/debug.out","a"))
if next(get) then return 1 end
sn = request["SCRIPT_NAME"]
static = string.gsub(sn, '^/blog/(.*)$', '/static/%1')
if (file_isdir(dr .. static) and file_isreg(dr .. static .. "/index.html")) then
-- f:write("cache hit on directory\n")
output_include = { dr .. static .. "/index.html" }
return 0
elseif file_isreg(dr .. static) then
-- f:write("cache hit on file\n")
output_include = { dr .. static }
return 0
end
-- f:write("no cache hit\n")
return 1
