Re: Technical question wrt lua_pcall() and errors

[Stefan Hett <stefan@...>]

The default lua error handler raises exceptions. So if lua_error() (i.e. 
it does not return). Hence ur FCGI_Finish() is not being called.
An option to go with might be to encapsulate the fcgi_handler()-call in 
a try/catch-block.
