It is simplest if the first CGI generates a FORM that POST's with HIDDEN variables to the second CGI. (BTW, put the HIDDEN variables right after FORM so they are not dropped. I made an HTML page where the SUBMIT was early, the middle processing was slow and the HIDDEN were at the bitter end of the FORM, and if the SUBMIT was hit immediately when it appeared, the HIDDEN were not honored. Probably a bug, but be aware.)
If you want to redirect to a POST CGI, you probably cannot pass FORM variables when you use the HTML META redirect, but you can call it yourself (your service acting like a browser/client and connecting to the server of the second CGI) and pass the appropriate encoded variables after the HTTP header and pass all or part of the content from the response to send to the browser as the whole response or as part of your response page. In most cases, you can use URL-encoding, but not always. For instance, file uploads must use POST with MIME encoding.
BTW, I am not a PERL web guy, just an HTTP/HTML hacker, but it is best to know what the PERL is doing for you. It has nice libraries, but they are just code that reads and writes bytes of HTTP and often HTML through a web server to a socket to the browser. The web server just passes the header and socket info in the environment and socket to stdin CGI input, and checks your return status before putting of the first line of the HTTP header out and sending your stdout response.

char *server(in) Virtual server.
_________________________________________________________________
DESCRIPTION
These routines are used to generate complete responses, including headers, approriate status codes, content types, and possibly short HTML
content messages for the most common HTTP error or status responses. They each coorespond to a particular HTTP status code, for example,
Ns_ConnReturnNotFound generates an HTTP 404 "Not Found" response. They all return NS_OK if the response was sent or NS_ERROR if an under-
lying routine failed.
The default behavior is to return an internal, server generated response possibly with a short English language message, for example "The
requested URL cannot be accessed by this server". This behavior can be modified by calling the Ns_RegisterRedirect to redirect responses
internally for the cooresponding HTTP status code to another URL on the server. The "redirects" server config section can be used to map
these redirects at startup
int Ns_ConnReturnBadRequest(conn, msg)
Returns an HTTP 400 response with the short HTML message "Invalid Request: The HTTP request presented by your browser is invalid."
The optional msg string, if present, is also included in the message body.
int Ns_ConnReturnForbidden(conn)
Returns an HTTP 403 response with the short HTML message "Forbidden: The requested URL cannot be accessed by this server."
int Ns_ConnReturnInternalError(conn)
Returns an HTTP 500 response with the short HTML message "Server Error: The requested URL cannot be accessed due to a system error
on this server."
int Ns_ConnReturnNoResponse(conn)
Equivalent to Ns_ConnReturnStatus(conn, 204).
int Ns_ConnReturnNotFound(conn)
Returns an HTTP 404 response with the short HTML message "Not Found: The requested URL was not found on this server."
int Ns_ConnReturnNotImplemented(conn)
Returns an HTTP 404 response with the short HTML message "Not Implemented: The requested URL or method is not implemented by this
server."
int Ns_ConnReturnNotModified(conn)
Equivalent to Ns_ConnReturnStatus(conn, 304).
int Ns_ConnReturnOk(conn)
Equivalent to Ns_ConnReturnStatus(conn, 200).
int Ns_ConnReturnStatus(conn, status)
Generates a response with the given HTTP status with no content.
int Ns_ConnReturnUnauthorized(conn)
Returns an HTTP 401 response with the short HTML message "Access Denied: The requested URL cannot be accessed because a valid user-
name and password are required." As "WWW-Authenticate: Basic realm=server realm" header is also included in the response.
void Ns_RegisterRedirect(server, status, url)
Redirect the above responses from the given server for the given status code from the simple internal messages described above to
the given internal url. The redirect is performed using Ns_ConnRedirect.
