Re: [cgi-devel] HTTP_RAW_POST_DATA

[<jc...@ol...>]

Hello Darren

Thanks for your answer.

I am unable to get that information. Below is my sample program. With my
browser I am getting "test" but if I use
echo '<doc><item>Some content.</item></doc>' | curl -X POST -H
'Content-type: text/xml' -d @- http://example...

I am getting nothing.
the above bash command against a php script does show the raw_post_data/

Do you think the progam is right? I am using nginx with supervisord
between the request and the fasctcgi app.
