Page anchor with mod_rewrite?

问题:

I'm trying to set up page anchors on a website that uses mod_rewrite (Apache2 running on Ubuntu Server 9.04).

My htaccess file looks like this:

RewriteEngine On
RewriteRule ^information.php/([A-Za-z0-9-]+)/?$ information.php?display=$1  [NC,NE]

If I was using regular URL's the query would look something like this: http://mydomain/information.php?display=faq#cost

I'm hoping to get something like this: http://mydomain/information/faq/cost

Is this possible? My understanding is that modrewrite ignores page anchors, and that the browser deals with it? I'm guessing that I can somehow use mod_rewrite to include the anchor information with the request, but I haven't been able to find anything documenting this and have been trying unsuccessfully to write it myself for hours.

Thanks!

Actually, if you want the resulting URL to have an anchor, then yes, it's possible. Just don't forget that in Apache configs, # marks the start of a comment.

If what you want is like this - user enters

http://example.com/page/anchor

and gets redirected to

http://example.com/?p=page#anchor

- you would need to use 301 Redirect, or something like that, so it wouldn't be transparent to the user.

Conclusion: While it is possible to write such a redirect rule, it can't be done entirely server-side. So I think you could point /information/faq to /information.php?display=faq and then use URLs such as:

http://example.com/information/faq#foo

which are almost what you want, plus they don't mess up caching.
