Rust

Example: Http.CloseAllConnections method

See more HTTP Examples

Demonstrates how to call the CloseAllConnections method. Rust

let http = chilkat::Http::new();

// Demonstrate 
let url = "https://finnhub.io/api/v1/quote?symbol={$symbol}&token={$api_key}".to_string();

// When the request is sent, the {$symbol} is replaced with "MSFT"
// and the {$api_key} is replaced with "1234567890ABCDEF"
let _ = http.set_url_var("symbol", "MSFT");
let _ = http.set_url_var("api_key", "1234567890ABCDEF");

let sb_json = chilkat::StringBuilder::new();
if http.quick_get_sb(&url, &sb_json).is_err() {
    println!("{}", http.last_error_text());
    return;
}

let status_code = http.last_status();
println!("{}", http.last_response_header());

// The response header contains this:

// Date: Tue, 19 Aug 2025 12:18:56 GMT
// Content-Type: application/json; charset=utf-8
// Transfer-Encoding: chunked
// Connection: keep-alive
// Content-Encoding: gzip

// The "Connection: keep-alive" header ensures the server keeps the connection open for subsequent requests.
// If the server responds with a "Connection: close" header, it indicates the connection will be closed after the response. 
// Consequently, Chilkat will also close the connection, requiring a new one to be established for any subsequent requests to the same server.

// If your application uses the same HTTP object instance to send requests to a different server, a new connection will be established with that server.
// Existing connections remain open, with Chilkat maintaining up to 10 open connections. 
// If all 10 connections are in use, Chilkat will close the least recently used connection to connect to a new server.

// Your application can explicitly close all open connections like this:
if http.close_all_connections().is_err() {
    println!("{}", http.last_error_text());
    return;
}

println!("Success.");
