ColdFusion Dropbox - How to get the token from the response URI - coldfusion

Question

I am trying to implement the OAuth with Dropbox from a ColdFusion application, and I managed how to call the Dropbox method to generate the access token, but... I don't know how to get the generated TOKEN from the response URI. I am getting something like this from Dropbox:
http://localhost/dropbox/generate_token.cfm#access_token=AAAAAAAAYVM_XdCYlbTz0gQOwQkWlg6TDXf84_5h4giikg6J-7Man&token_type=bearer&uid=267693&account_id=dbid%3AAABeDMm-BN0n1DofLZz9kPZAipnQ
How to I retrieve the URL variables in this case? I mean if I do a
<cfdump var="#URL#">
I am getting an empty struct. If I do a
<cfdump var="#CGI#">
I still don't see any of the URL retrieved parameters in the structure. How do I get the variables and their values from the Dropbox response?

UPDATED
At some point I thought I found a way to read the URL but now - for no reason - this doesn't work anymore! I didn't change anything but the solution below doesn't work anymore.
I can read the full URL with JavaScript using document.location but this means to do an extra submit to a ColdFusion page and I don't want to do this. I want to get the Dropbox token from the URL and save it to the database directly in this page...
Any new ideas please?
SOLUTION THAT SEEMED TO WORK AT SOME POINT ...
I found a way to get the URI string using this:
<cfset objRequest = GetPageContext().GetRequest().getParameterMap() />
<cfdump var="#objRequest#">
<cfoutput>
<cfloop collection="#objRequest#" item="i">
<p>
#i# - #objRequest[i][1]#
</p>
</cfloop>
</cfoutput>
From now on, I know how to get the values returned by Dropbox.

I found a way to get the returned parameters by reading the browser URL with JavaScript, so in two steps: first, parse and extract the full URL including the part after the # sign (I found this has a name and it is called the "URL fragment") and second, create a JavaScript form with parsed parameters and resubmitted to the server. Here is the code:
<cfparam name="FORM.action" default="">
<cfif FORM.action IS "save_token">
<cfdump var="#FORM#">
<cfelse>
<form name="main" id="main" method="post">
<input type="hidden" name="action" id="action" value="save_token">
</form>
<script type="text/javascript" language="javascript">
<!--
var parameters = window.location.hash.substr(1).split("&");
function addHidden(theForm, key, value) {
// Create a hidden input element, and append it to the form:
var input = document.createElement("input");
input.type = "hidden";
input.name = key;
input.value = value;
theForm.appendChild(input);
}
// Form reference:
var theForm = document.forms["main"];
for (var i=0; i<parameters.length; i++) {
// Add data:
addHidden(theForm, parameters[i].split("=")[0], parameters[i].split("=")[1]);
}
theForm.submit();
//-->
</script>
</cfif>
