How to rewrite a URL with in it?

3 Views

I have a (wordpress) blog where after commenting the users are redirected back to the page with an anchor to their comment. Should look like this:

http://example.org/foo-bar/#comment-570630

But somehow I get a lot of 404 ins my logfiles for such URLs:

http://example.org/foo-bar/%23comment-570630

Is there a way to write a .htaccess rewrite rule to fix this?

Bonus question:
Any idea why this happens and what I can do about it?

  1. %23 is the URL encoded representation of #. I suspect your rewrite rules will not satisfy %23. You ought to investigate how the response is being constructed. Specifically, any URL encoding functions.

    However, it would be possible to solve your issue with a rewrite rule. Understand that you’ll be returning two responses to the client after a comment is submitted. This is why it is preferable to correct the first response.

    # http://example.org/foo-bar/%23comment-570630 -> http://example.org/foo-bar/#comment-570630
RewriteCond %{REQUEST_URI} %23comment-d+$
RewriteRule (.+)/%23-comment(d+)$ http://host/$1/#comment-$2 [R=301]

    It’s untested, but should work (I’m unsure about escaping % as it has special meaning in mod_rewrite).

  2. Have you tried the B Flag?

    RewriteCond %{REQUEST_URI} %23comment-d+$
RewriteRule (.+)/%23-comment(d+)$ http://host/$1/#comment-$2 [B,R=301]

    untested with your specific case, but used for a related problem.
