Thanks Kurt.

The patch compiled and got installed fine. I no longer get an unknown directive error msg. However, the client's POST request of 1.5M of data still gives me this error "413 Request Entity Too Large"

even though I added "fastcgi_request_buffering off;"

location / {
include fastcgi_params;
fastcgi_request_buffering off;
fastcgi_pass 127.0.0.1:9000;
}

Here was my test:
curl -X POST -T testfile -v 'http://localhost:80/'

> POST /testfile HTTP/1.1
> User-Agent: curl/7.19.7 (i386-redhat-linux-gnu) libcurl/7.19.7 NSS/3.16.2.3 Basic ECC zlib/1.2.3 libidn/1.18 libssh2/1.4.2

Has anyone tried the fastcgi_request_buffering ... or am I missing something? Thanks.
