Ok this is the http request that you are making right? If that is the case, request header should have “Cookie:” not “Set-Cookie” in them, because “Set-Cookie” is a header that is received from the web servers that makes your client create and save that cookie on your machine locally. Regarding the CRLF are you adding one also at the end? According to http there will be one CRLF at the end of each header and one additional CRLF between the last header and the request body. So i would suggest you to try adding one or two CRLF at the end of the last header. Also have you tried passing the same parameters(cookies, etc) with wget and curl to download the file?
