When using the Curl library for HTTP requests, maintaining persistent connections can significantly improve performance by reducing connection overhead. This article explores how to establish and manage keepalive connections using Curl.
By default, Curl reuses connections for subsequent requests when the same Curl handle is used. This means that you can reuse the handle for multiple requests without needing to re-establish the connection each time.
Curl does not require any special options to enable keepalive connections. However, if you need to customize the keepalive parameters, you can use the following options:
While Curl manages keepalive connections automatically, there are a few potential pitfalls:
By reusing Curl handles and considering the options mentioned above, you can establish and maintain keepalive connections with your HTTP requests. This can significantly reduce overhead and improve performance, especially when working with high-frequency requests.
