If you get the 303 See Other Error, you're not alone.
The 303 See Other Error is a pretty common error that appears when you try to access a page on the Internet.
It's a "classic" status code that can be time-consuming to fix.
This article will show you what the 303 See Other Error is exactly and how to solve it.
Let's get started!
Let's first try to understand what HTTP status codes mean.
In a nutshell, the Internet has two major players: servers and clients. Let's say that you're using your browser, Google Chrome, to access a web page. You're actually accessing the Internet through a web client.
The server is the thing on the other side of the communication that receives your request to access a page.
An HTTP status code is exchanged between the server and the browser every time you make a request to your server to access a resource.
There are five different classes of HTTP response status codes. Although somewhat different. they all inform a user whether a specific HTTP request has been successfully completed.
The five core status codes include:
1xx status codes: Informational requests
2xx status codes: Successful requests
3xx status codes: Redirects
4xx status codes: Client errors
5xx status codes: Server errors
The 303 See Other error belongs to the 3xx status codes group that are redirects. When a user or search engines come across a 3xx status code, they will be redirected to a different URL from the initial. Some status codes – like the 301 Moved Permanently, 307 Temporary Redirect, and 308 permanent redirects – affect your user experience and SEO performance.
They're different from status codes in the 4xx group – like the 404 Not Found error– indicating something on the client-side of things is the issue. They're also different from codes in the 5xx group – like the 503 status code– that indicate something on the server-side of the things is the cause of the problem.
While status codes in the 4xx and 5xx groups mean that a problem occurred on the server or with the client, 3xx status codes don't indicate an issue. Instead, they appear due to the server's behavior or configuration.
As we've mentioned earlier, the 303 See Other indicates that something has gone wrong within your application server. With that said, we can say that nothing on the client-side of things is causing the issue.
As some of the status codes in the 3xx group can negatively affect your SEO and user experience, fixing them is critical.
The good news is that most modern browsers automatically detect a 303 See Other response code and process the redirection action to the new URI automatically. This means that there's not much you can do to fix it.
However, if the redirection doesn't happen automatically, here are some troubleshooting tips that may help you fix the server-side issue:
If you're certain that the issue isn't on your side of things, the first thing to do is check if there are any unintentional redirect instructions in your web server's configuration files.
Your application is either running on Apache or Nginx web servers. If it turns out that it's an Apache server, then both apache_server and .htaccess need to be checked.
On the other hand, if you're using Nginx, only one file needs checking: namely, nginx_conf_. After you locate the files, search for 303 status codes and see if anything appears. If it does, you need to modify it. You either want to remove it entirely if you don't need the status code or apply it to a specific page.
A 303 See Other is an HTTP status code indicating that the resource you requested is located at another URI (address) using the GET HTTP method.
The best way to fix the 303 See Other status code is to:
Confirm your server configuration
Debug your application code
