Browser redirects, especially 301 “permanent” redirects, are essential to all good web applications. Regardless of language, browser redirects can:
- provide safe URL forwarding to gather GET and POST variables and process them without risking data and processing integrity by a browser refresh
- send users and search engine bots to the new location of a page or entire website
- maintain search engine rank and avoid 404 errors
Here’s the list of browser redirects using various languages:
