HTTP Redirect

An HTTP redirect occurs when a server tells a client to access a different URL. Redirects are typically indicated using status codes like 301 (permanent) or 302 (temporary).

Also known as: URL redirection, 3xx redirects.

Comparisons

• 301 vs. 302 Redirects: 301 is for permanent changes, while 302 is for temporary ones.

• Server-side vs. Client-side Redirects: Server-side uses HTTP codes; client-side often relies on JavaScript.

Pros

• Seamless navigation: Guides users or clients to updated URLs.

• SEO retention: Helps maintain search rankings for moved content.

Cons

• Performance impact: Additional round trips can slow access.

• Misconfiguration risks: Improper redirects can cause loops or errors.

Example

A website redirects outdated product pages to new ones using a 301 redirect.
