Interface

int  WebRequest2(
   const string      method,                // HTTP method
   const string      url,                   // URL
   const string      headers,               // headers 
   int               timeout,               // timeout
   char              &data[],               // the array of the HTTP message body
   char              &result[],             // an array containing server response data
   string            &result_headers        // headers of server response
   const int         port=NULL,             // Define custom port
   const bool        allowInsecure=false,   // Allow self signed certs
   const bool        useSSL=NULL            // Use SSL encrypted connection
   );

Return value HTTP server response code or -1 for an error.

Remarks

If allowInsecure is set to true the following flags are set:

SECURITY_FLAG_IGNORE_UNKNOWN_CA
INTERNET_FLAG_IGNORE_CERT_DATE_INVALID
SECURITY_FLAG_IGNORE_CERT_CN_INVALID
SECURITY_FLAG_IGNORE_REVOCATION

Please note that these Settings make SSL nearly useless. Therefore this flag should never be used in a environment where security matters! For reference check out: https://docs.microsoft.com/en-us/windows/desktop/winhttp/option-flags

The import "kernel32.dll" is used to retrieve the error messages.

Usage
