Wikipedia link format ?

[conradk]

Hey,
DOes anybody know why HTML generated by wikipedia creates links like;

<a href="//es.wikipedia.org/">Link name</a>

What is the doubleslash before the URL all about ?

Thanks for any help you can offer

Best regards,
CK

Might be a typo I have seen this before though.

Well, Twitter uses it too.

And PHP doesn't think this is a valid URL when using the FILTER_VALIDATE_URL, which is kind of idiotic IMO.

Anyways, thanks for answering

I believe this can be used when you don't care whether http or https is used.

That makes sense, but surly just / would do the same thing

I would if it is on the same server

// is used when you don't care whether it uses https or http. It defaults to what protocol you are currently using.
