POST requests not working in FastCGI - with potential fix

[brendonm]

When a POST request is sent to httpd, none of the Content-X headers are being sent through FastCGI, and I'm not sure that the content itself is sent either. This effectively eliminates the possibility of using form submissions, which are a very important part of any web application.

To clarify, the Content-Type and Content-Length headers are being sent through FastCGI as CONTENT_TYPE and CONTENT_LENGTH respectively. This differs from the nginx implementation which also includes them as HTTP_CONTENT_TYPE and HTTP_CONTENT_LENGTH.

It is preferable from an application point of view to have these headers come through with HTTP_ prefix, as they can then use this prefix to show all the headers sent from the client without having to apply additional logic.

Possible fix could be to comment out the following lines:

httpd/server_fcgi.c: 649

// if (strcasecmp(key, "Content-Length") == 0 ||
// strcasecmp(key, "Content-Type") == 0) {
// if ((name = strdup(key)) == NULL)
// return (-1);
// } else {
if (asprintf(&name, "HTTP_%s", key) == -1)
return (-1);
// }
