Using DNS to redirect to another URL with a path [closed]

No, what you ask is not possible. DNS is name resolution system and knows nothing about HTTP.

if you use AWS, a redirect like

mail.foo.com --> mail.google.com/a/foo.com

can be setup as follows:

1. in s3, create an empty bucket "mail.foo.com"
2. under Properties -> Static Website Hosting, set "redirect all requests to: mail.google.com/a/foo.com"
3. in route53, create an A record "mail.foo.com"
4. enable "alias", and set alias target to the "mail.foo.com" bucket

not a pure DNS solution, but it works ;)

But be aware of, the redirect skips all the URL parameters e.g.: ...?param1=value1&param2=value2

I realize this is an old thread but FWIW, incase someone else is looking for a way to do this.

While dns does not understand the path portion of the url, it will understand subdomains, so instead of:

www.proof.com IN CNAME www.proof-two.com/path/index.htm

You could use:

www.proof.com IN CNAME proof.proof-two.com

then go to wherever you host proof-two.com and set it to point proof.proof-two.com to www.proof-two.com/path/index.htm.

Edit

It seems that it's my provider (OVH) who allows that kind of redirect within its infrastructure.

See : https://docs.ovh.com/gb/en/domains/redirect-domain-name/

I'm keeping the answer below for the sake of archiving, but it doesn't provide any meaningful information for other DNS providers.

Original answer

I did that using a TXT record.

To redirect foo.bar.com to foo2.bar.com/path, just add foo IN TXT "1|foo2.bar.com/path" in your bar.com DNS zone.

It also keeps the url paths and parameters. So if you try to access foo.bar.com/hello?foo=bar, you'll be redirected to foo2.bar.com/path/hello?foo=bar.
