May be a bug in handler.lua

[lingbl]

code in handler.lua:

if self.callback then
response:statusCode(200)
response.headers = {} -- response._headers = {} ???????????????????????????
response:addHeader('Content-Type', 'text/html')

self.callback(request, response)

end

If the code before it (while trying to serve a file), had already set some headers before it failed for some reason, then the headers get cleared. This makes sense to me.

Though I agree that the mixing of file handling and callbacks is not very clean, can could be improved upon, which would also fix your concern.
