but when i use pure Command::new("curl") i can see it useing http2 and TLSv1.3

let mut curl_command = Command::new("curl");
curl_command
    .arg("--keepalive-time")
    .arg("120")
    .arg("--verbose");

here I my current code

    let proxy_url: Uri = proxy
        .parse()
        .context("Failed to parse proxy URL")?;

    let isahc_client = IsahcHttpClient::builder()
        .version_negotiation(VersionNegotiation::http2())
        .tcp_keepalive(TokioDuration::from_secs(300))
        .timeout(TokioDuration::from_secs(60)) // Example of setting a request timeout
        .proxy(proxy_url) 
        .build()?;

There's not currently a way to specify which TLS version to use, however this is something that I believe is already implemented in the version 2 branch (currently on hold).

It is also worth noting that Isahc uses libcurl, and not the curl command, so in a way, Isahc and the curl command are both equally consumers of libcurl.

It could very well be just differences in which libcurl version is being used. Isahc by default uses a bundled libcurl and not the one installed on your system. I would check to see which versions of libcurl are being used in both places. You can see the libcurl version used by Isahc by checking the return value of version.

You can also disable the static-curl default crate feature to get Isahc to link to your system-wide libcurl, which might behave more similarly to the curl command.

@sagebind thanks for quick reply

Isahc version: isahc/1.7.2 (features:default,encoding-rs,http2,mime,static-curl,text-decoding) libcurl/8.9.0-DEV SecureTransport zlib/1.2.12 nghttp2/1.61.0

but I will run my code in Docker so it more important my docker will run TLS 1.3 then on my MacBook

how I can disable the static-curl?

I have try this
isahc = { version = "1.7.2", default-features = false, features = ["http2", "mime", "text-decoding"] }
still same

thanks this WORK
isahc = { version = "1.7.2", default-features = false, features = ["http2", "mime", "text-decoding"] }

for docker do I need to add something ?

SSL connection should be this SSL connection using TLSv1.3 / TLS_AES_256_GCM_SHA384 / x25519 / RSASSA-PSS

but I am getting this SSL connection using TLSv1.3 / AEAD-CHACHA20-POLY1305-SHA256 / [blank] / UNDEF

@sagebind can you help me little bit confuse
