How to Website Third Party scripts.js cache controll ?

To set cache control headers for third-party scripts in Java, you'll need to configure your web server to include the appropriate headers in the HTTP response. Java code itself is typically used to handle the server-side logic and processing of requests, but it does not directly control HTTP response headers.

If you're using a Java-based web framework like Spring Boot or Java Servlets, you can set the cache control headers in your server-side code to control caching behavior for third-party scripts.

Here's an example of how you can set cache control headers in Java Servlets:

    <script type='text/javascript'>

//<![CDATA[

import java.io.IOException;

import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

@WebServlet("/third-party-script.js")

public class ThirdPartyScriptServlet extends HttpServlet {

    @Override

    protected void doGet(HttpServletRequest request, HttpServletResponse response)

            throws ServletException, IOException {

        // Set cache control headers for third-party script

        response.setHeader("Cache-Control", "public, max-age=31536000");

        

        // Set other response headers if needed

        response.setContentType("text/javascript");

        

        // Write the content of the third-party script here

        // You can read the script from a file or generate it dynamically

        

        // Example:

        String thirdPartyScript = "console.log('This is a third-party script.');";

        response.getWriter().write(thirdPartyScript);

    }

}

//]]>

</script>

In this example, the doGet method of the ThirdPartyScriptServlet sets the Cache-Control header to allow public caching and sets the cache's maximum age to one year (in seconds) for the third-party-script.js resource. You can adjust the cache duration as needed.

Please note that this example assumes that you have a servlet mapped to the URL pattern /third-party-script.js. You should configure your web server or servlet container to map the servlet to the appropriate URL and adjust the script content according to your actual third-party script.

Additionally, you can use similar cache control header settings in other Java web frameworks like Spring Boot, depending on how you handle the HTTP response in your controller or handler methods.

Website Max Cache control:

<script type='text/javascript'>

const express = require('express');

const app = express();

const oneYearInSeconds = 31536000;

app.use(express.static('source29.blogspot.com', { maxAge: oneYearInSeconds }));

</script>

Remember that for third-party scripts hosted externally (e.g., loaded from a CDN), you won't have direct control over the cache control headers. You can only set cache control headers for third-party scripts hosted on your own server.
