For SEO purposes, we should issue 301 & 302 status codes only in Gateway ckan redirection module

For SEO purposes and avoid potential compatibility issues, we should avoid using newer redirection status codes (e.g. 307) and only use:

• 301: Permanent redirect
• 302 Temporary redirect
• 303 Temporary redirect but the request should be GET

Closed --- as 307 should be supported widely by now
