Download curl 8 2 0

Hi @bagderI am using curl with --http3-only option to download file from nginx server.From below curl man page and help page i came to know that using --http3 will allow to fall back ,--http3-only will not allow to fallback but seems to be with --http3-only also curl is falling back and using http1.1man curl:---http3-onlysion on its own. Use --http3 for similar functionality with a fallback.Instructs curl to use HTTP/3 to the host in the URL, with no fallback to earlier HTTP versions.This option will make curl fail if a QUIC connection cannot be established, it will not attempt any other HTTP version on its own --http3 Use --http3-only for similar functionality without a fallback.Tells curl to try HTTP/3 to the host in the URL, but fallback to earlier HTTP versions if the HTTP/3 connection establishment failscurl --help all :---http3 Use HTTP v3--http3-only Use HTTP v3 onlyroot@ubuntu:~# curl -# -v -k --http3-only -o index.html 127.0.0.1:443...Connected to 127.0.0.1 (127.0.0.1) port 443 (#0)ALPN: offers http/1.1} [5 bytes data]TLSv1.3 (OUT), TLS handshake, Client hello (1):} [512 bytes data]TLSv1.3 (IN), TLS handshake, Server hello (2):{ [88 bytes data]TLSv1.3 (OUT), TLS change cipher, Change cipher spec (1):} [1 bytes data]TLSv1.3 (OUT), TLS handshake, Client hello (1):} [512 bytes data]TLSv1.3 (IN), TLS handshake, Server hello (2):{ [155 bytes data]TLSv1.3 (IN), TLS handshake, Encrypted Extensions (8):{ [21 bytes data]TLSv1.3 (IN), TLS handshake, Certificate (11):{ [768 bytes data]TLSv1.3 (IN), TLS handshake, CERT verify (15):{ [264 bytes data]TLSv1.3 (IN), TLS handshake, Finished (20):{ [52 bytes data]TLSv1.3 (OUT), TLS handshake, Finished

GET request method and will not download the body of the HTTP response message. Curl GET HTTP headers example curl -I Getting JSON using Curl To receive data in JSON format with Curl, you must pass the "Accept: application/json" HTTP header to the server. If you do not pass this header, the server may automatically choose your client's most appropriate data type and return the data in a different format. The following is an example of getting JSON from a ReqBin echo URL: Curl GET JSON example curl -H "Accept: application/json" Checking if the target URL supports HTTP/2 using Curl To check if the target URL supports HTTP/2 using Curl, you can send a Curl HEAD request along with the --http2 command line parameter. Curl HTTP/2 support check curl -I --http2 In the response, you will see the HTTP/2 200 status line if your server supports the HTTP/2 protocol or HTTP/1.1 200 otherwise. Sending cookies along with a GET request using Curl You can send cookies to the server using the -b command-line option followed by a string with the cookie or the name of the file containing the cookies. Curl GET Request Example with Cookies curl -b "session=eJwlzj0wMQG7eO4Q" Getting a specific range of bytes from a resource using Curl To get a specific range of resource bytes from a target URL using Curl, you can use the -r command line option. Curl example to get a specific range of bytes curl -r 0-15000 Limiting the maximum transfer rate for Curl GET requests You can use the-- limit-rate command line option to limit the maximum transfer rate for uploading and downloading files in Curl. By default, the speed is measured in bytes per second, but you can specify the speed in kilobytes (K), megabytes (M), or gigabytes (G) using a
