How to stop your web scraping process
There are a few ways you can stop your web scraping process. You can use a reverse proxy to serve the pages you want to scrape from, keep track of the URLs your scraper is visiting, or disable cookies.
To use a reverse proxy, create a file called “proxy.php” in your scraper’s root directory and add the following code:
addOnHost( ‘localhost’ ); $http->addOnPort( 8080 ); $url = ‘https://www.google.com’; $proxy = new HTTP_Proxy($http);$proxy->pass($url); ?>
Now when you want to scrape Google, all you have to do is visit http://localhost:8080/ proxy.php and it will take care of everything else. Of course, you’ll need to change localhost to the IP address of your machine if you’re using a public proxy.
If you’re using cookies to track which pages your scraper is visiting, you’ll need to get rid of them before scraping. You can either delete all cookies in your browser or set a cookie timeout so that the scraper doesn’t keep hitting the same page over and over again.
Finally, sometimes it’s useful to disable JavaScript completely in order to prevent cross-site scripting attacks. To
