Where to find bookmark in controller

Rails
1

If I do a
link_to ‘XYZ’, ‘/usage/Faq.html#GB_limit’
in my view …

can I detect “GB_Limit” in my controller? Where?

I know I can do
link_to ‘XYZ’, ‘/usage/Faq.html?bookmark=GB_limit’
and I can find GB_limit in params[:bookmark].

Not to my knowledge. I believe – and I hope someone will correct me if
I’m wrong – that the browser removes the #fragment section of the URL,
and merely does a HTTP GET ‘/usage/Faq.html’, so that the server never
even sees the #fragment. Therefore, the only way I’m aware of to
process the #fragment is to use client-side JavaScript.

(BTW, you should really be using lowercase for your HTML filenames, or
else you’re likely to run into case sensitivity issues.)

Right. The ?query=string is meant for the server. The #fragment is
meant for the client. That’s just how HTTP URLs work.

I used to think that too, but then I tested it a few months back and
found every browser I tried worked fine with incorrect case in a URL.

http://example.com/Home.html worked when the actual URL was
http://example.com/home.html

I still go all lowercase just out of habit… looks cleaner too.

I think if you really need to pass the (window.location.hash) to the
server when you have to go with JavaScript.
In your case since you have a bookmark inside the link href, I would
create a custom XHR request with passing a bookmark as a GET
parameter.
I hope that something like this can be helpful to you:
jQuery(function($) {
$(’#your_special_link_with_bookmark’).click(function() {
var href = this.href;
$.get(href, {‘bookmark’ : href.substr(href.indexOf(’#’) + 1)})
})
})
I didn’t test the example, but something like this is a very small
hack and you can adjust it to your needs.

Thanks, Ivan Povalyukhin

AFAIK this is server-dependent, not browser-dependent – that is, some
servers are case-sensitive and some are not.

For example, my website is hosted on a case-sensitive server (Apache on
some sort of *nix). I just tried typing in
http://www.marnen.org/Music.html and got an error (Firefox 3.6, Mac OS X
10.6). marnen.org: Homepage of Marnen Laibow-Koser , however, gives the expected
page. Do you get different results? If so, in what browser?

It’s best to always treat your server (and browser) as if they’re
case-sensitive.
