Deduplicate doc URLs

[SimonSapin]

There are at least three sets of URLs that give the same thing:

http://doc.rust-lang.org/std/
http://doc.rust-lang.org/nightly/std/
http://static.rust-lang.org/doc/master/std/

One of the should be picked and the others redirect to it.

Related, but I believe not quite duplicate: #9461, #12466, #14466, #18558.

The second are synonymous on purpose, and I'm not sure the third is even exposed anywhere, exactly

[tomjakubowski]

Presumably /std/ will be (or redirect to) the stable channel docs, right?

[steveklabnik]

Yes, once we have a stable channel :)

[SimonSapin]

I’d like to revisit the decision to have URLs synonymous on purpose, which can be bad for search engines, and use redirects instead.

[steveklabnik]

There's a second ticket open for rel=canonical, but I think that the reason that there can't be redirects is that they're just files on S3. /cc @alexcrichton

[SimonSapin]

S3 seems to support redirects: https://aws.amazon.com/blogs/aws/amazon-s3-support-for-website-redirects/ (though I haven’t looked into details).

[alexcrichton]

Last I looked into redirects they won't work for static.rust-lang.org, but that site is not linked from anywhere so I don't think that we should be worried about it. The other two I feel like are fine to have, we can use the rel=canonical trick to disambiguate, but I don't want either to go away.

I'll link to a comment I've made before about duplicate URL structures on rust-lang.org.

This is something you should strongly consider fixing.

Right now we have stable docs available in two locations:

http://doc.rust-lang.org/std/
http://doc.rust-lang.org/stable/std/

On the infrastructure side we can make one redirect to the other. Does the docs team have a preference as to which is the canonical version?

[tomjakubowski]

Did you mean to say stable docs are available at /std/ and at /stable/std/? Or are the docs at /nightly/std/ docs for the stable distribution?

[alexcrichton]

Oops, yes!

Let's try this: @rust-lang/docs
