constant-httpd filewhere file is a file name.
constant-httpd reads an HTTP request message from standard input, and prints file in response.
Before reading any input, constant-httpd changes the working directory to that named in the $ROOT environment variable, performs chroot to the current directory, and then sets its group id and user id to the numeric values given in the environment variables $GID and $UID, typically set with envdir. If it cannot carry out these operations, constant-httpd complains to standard output and exits 111. If the file argument is missing it silently exits 100.
If it encounters an error in reading file, constant-httpd exits 23. If it encounters another error processing a request, constant-httpd exits 21. Otherwise, it exits 0.
constant-httpd accepts HTTP/0.9, HTTP/1.0, and HTTP/1.1 requests. For a request with the host name host, constant-httpd looks for ./host/file, after replacing /. with /: and // with / in ./host/file. For a valid request lacking a host name, constant-httpd uses 0 as the host name.
If the environment variable $REQUESTHOST is set, then constant-httpd uses its value as host, overriding any host given in the request.
