Catch Double Forward Slashes in the URL Path

[FelicianoTech]

URLs such as the following, http://example.com/blog//my-first-post/, passes HTML Proofer. This causes an issue for me because double forward slashes aren't part of proper URLs. Some servers will process it, some will throw a 404.

HTML Proofer should catch a double slash in the path as an error. Or at least, put that functionality behind a flag.

Note, this is not to be confused with protocol relative URLs, //example.com/blog/my-first-post/. That's a perfectly fine URL. I'm not complaining about that nor should support for that change.

That URL is perfectly valid and therefore should not be flagged by html-proof as an error.

Relevant authority: RFC 3986

My recommendation is to close this issue.

I'm going to have to abide by the RFC on this one, sorry.

However, it's also possible to write your own tests, so perhaps that will work for you? https://github.com/gjtorikian/html-proofer#custom-tests

I find it difficult to read through that RFC but it everyone is in agreement that it's allow, okay. I'll look into a custom test.

@FelicianoTech Don't read the RFC, here is a quick experiment you can try (I should probably put this on SO somewhere):

cat > tmp.php <<'EOF'
<?php
echo $_SERVER['REQUEST_URI'];
EOF
php -S localhost:4000 tmp.php

Now open your browser to http://localhost:4000/hello//world

It loads.
