I realized that I have been doing the same thing (i.e., using the FastCGI
handler without the AddHandler and FastCgiServer directives specified for
Apache. But when I add them in, it breaks RT. I get the following message
in my Apache error_log file:

[Sun Oct 21 15:28:19 2001] [error] [client 63.205.xxx.yyy] (2)No such file
or directory: FastCGI: incomplete headers (0 bytes) received from server

About 1/4 of the time, I also get what *should* have been returned to the
web client (namely, the HTML login page) also in error_log. Usually the
"incomplete headers" business with FastCGI means that the client isn't
correctly outputting HTTP headers, but that doesn't appear to be the case
here. I have tried messing around with the various timeout settings for
the FastCGI directives in httpd.conf, but I've had no success. I'm using
the latest FastCGI (2.2.10) with Apache 1.3.19. I know that the FastCGI
mod works because I'm using a couple of other FastCGI apps with no

The "no such file or directory" bit of the error message has me confused,
too. I'm not sure which file or directory is being referenced. Maybe some
kind of permissions problem?

Any suggestions?
