What is a 400 Bad Request?
A 400 error is a type of HTTP bad request. You might be curious, what exactly is a bad request? Well, it means the server couldn’t understand or process what your browser was asking for due to incorrect or incomplete information.
To dive a bit deeper, It’s an error message you see when something goes wrong with how your browser asks for a webpage.
Think of it like entering the wrong web address when trying to visit a site. The website’s server tries to understand the request, but if it’s incorrect or incomplete, the server sends back a “400 error” to let you know it couldn’t process it.
Common Causes of 400 Bad Request Errors
Incorrect URL
You might accidentally type a web address wrong. A simple typo leads to a 400 error, as the server can’t find what you’re looking for.
Large Request Size
When you send too much information to a server—like uploading a big file—it struggles to handle it. This often triggers a 400 error.
Invalid Cookies
Cookies enable websites to recognize you. However, if they become corrupted or outdated, they confuse the server. Consequently, an HTTP 400 error occurs.
Incomplete Requests
If your browser doesn’t send all the necessary information—like missing parameters—the server won’t know how to respond, leading to a 400 bad request error.
Firewall Restrictions
Occasionally, security software or firewalls block certain queries. If your query appears suspicious, the server may return a 400 error.
Unsupported Media Type
When you try to upload a file type that the server doesn’t accept, it can’t process your request. This results in an HTTP 400 error.
