I've been using the following code to parse the headers out of an Rackspace API response for 18 months now. self._response is a string containing the whole http response.
local headerString = self._response:match("[%g ]+\r\n([%g \r\n]+)\r\n\r\n") .. "\r\n"
if headerString == nil then error("Couldn't find header") end
for k, v in headerString:gmatch("([%a%d%-]+): ([%g ]+)\r\n") do
if k == nil then error("Unparseable Header") end
headers[k] = v
end
return headers
Thanks,
Kevin
