What is a 400 Bad Request?
A 400 Bad Request error occurs when the client (usually a web browser) sends an invalid request to a server. This can happen due to various reasons such as mismatched headers, malformed data, or incorrect method usage.
Why Plain HTTP is a Problem
Plain HTTP uses the plain text protocol which can be easily intercepted and read by an attacker. This makes it easy for them to exploit vulnerabilities such as session hijacking, CSRF attacks, or data theft.
Fixing It Right: How to Use HTTPS
To fix 400 Bad Request errors using plain HTTP instead of HTTPS, simply switch from the default protocol. You can do this by updating your DNS settings or configuring your web server to use HTTPS.
