Hi,
I am using wininet.dll API to send http requests. Everything working fine - I am able to send a request and receive a response, but I am unable to pass any parameters with the request.

Meaning :
POST /resource...
...headers... CRLF
CRLF
myParameter=value CRLF

the wininet API has a function HttpSendRequest (hande, headers, headersLength, data, dataLength)

for some reason the data does not arrive or not sent, however the CONTENT-LENGTH is added to headers.

Any suggestions ?
Thank you in advance

Try this:

char pHeader[] = "Content-Type: application/x-www-form-urlencoded\r\n";

HttpAddRequestHeaders( m_hData, pHeader, strlen( pHeader ), HTTP_ADDREQ_FLAG_REPLACE | HTTP_ADDREQ_FLAG_ADD );

before HttpSendRequest - this helped me, probably it will help you.
