    if Support you can use The If-Modified-Since HTTP Header

    The “If-Modified-Since” HTTP header is sent from an agent
    (browser/bot) to the web server in order to know if the requested page
    has been changed since its last visit. The server responds with a 200
    code (Ok) if the page has been modified or with a 304 code (Not
    modified) if the page has not been modified.

    Refer The If-Modified-Since HTTP Header, where given an easy way to check if a web server supports the if-modified-since HTTP header
