With the client browser asking for the current redirect, the server still has control. This results in slightly greater net traffic, but unless your or something similar, the extra traffic is negotiable. However, if you use a “temp” redirect the browser will ask the server for a new redirect each time it attempts to load the page. The only way to correct the problem is to have each and every user clear their cache. Thus the server has no way to control the client anymore. Thus, if you use a permanent redirect the client’s browser does not contact the server for the initial URL, the client browser only sends what it stored for the redirect to the server. It will do the redirect, but it marks the redirect as expired immediately after that use. If you use a “temp” redirect the browser stores the redirect as expired. If you use a “permanent” redirect, the browser stores the redirect indefinitely. (There are more, but I have not investigated them at this time. There are two types of redirects “temp” (302) and “permanent” (301). I’ve look into this very extensively recently. Clear General RedirectsĪfter all of that, I would go through the steps outlined in this blog post to clear any non-HSTS redirects. If you do have an HSTS value stored, you can use Delete domain security policies to remove it. Using Query HSTS/PKP domain you can check for a stored HSTS value by domain. Clear any stored HSTS header in ChromeĪs mentioned in Alex’s post, you can go to chrome://net-internals/#hsts to manage stored HSTS values. If you are getting an HSTS header, you need to modify your server to stop sending this header. curl -sIL | grep 'Strict-Transport-Security' || echo "HSTS header not found" If found it displays the HSTS header, if not it displays a not found message. If you like using the command line (and you have `curl` and `grep` installed), the following command pulls in the headers and looks for the HSTS header. You’re looking for a line that starts with Strict-Transport-Security: If you’re not familiar with how to view your headers, you can check out View HTTP headers in Google Chrome on StackOverflow. Recognizing this isn’t always possible, if I were trying to clear the redirect I would do the following. My first choice in this situation would be to add an SSL certificate so the sites run on HTTPS. I’d love to hear about other ways people are clearing these cached urls. How do You Deal with Cached Redirects in Chrome?

How to Clear a Redirect from Google Chrome’s Cache After you add an index page, you’ll find you are still redirected to /cgi-sys/defaultwebpage.cgi and this redirect is surprisingly difficult to clear. If you visit the new site before adding an index page, you are redirected to /cgi-sys/defaultwebpage.cgi. Personally, I’ve found this often arises when creating a new site using cPanel. However, in the content of the page is included a redirect meta tag like In this case, the server responds with a 200 status code indicating that the page loaded just fine. When the Content Contains a Meta Refresh Redirect The problem is that even if the server stops sending the 301 redirect, Chrome will continue redirecting to the new url. Once Chrome caches this response, it will automatically redirect to the new location without checking with the server. A common redirect header is the 301 redirect http status code. These headers can include an instruction to redirect the visitor to another page. When a server sends a webpage it includes headers. When the Website Returns a HTTP Status Code Redirect There are generally two situations where this occurs. This is a logical decision, unfortunately the lack of any obvious mechanism to clear these redirects is frustrating at times. Google Chrome caching redirects, is a known behavior and not one that is planned to change.
