Re: Technical question wrt lua_pcall() and errors

[Romulo <romuloab@...>]

It might not be the case, but it happened to me that the httpd's error
handler made a second request to the fastcgi url, thus, repeating the
response.
I'm sorry to don't quite remember it, but I guess it was the
favicon.ico (I know, the browser is the one to blame, but still..)
Perhaps you could print the request URI on top of each fcgi accept loop.

--rb

Ps: sorry for the formatting, I'm using a cellphone.
