Dotnet Return Url Missing Parameter

Here's a head-scratcher:
I have a Dotnet Application which signs a user out after a certain inactive time period. A JavaScript function using an action defined in the relevant CSHTML sends the user to a certain controller method which will sign them out.
When the JavaScript code decides that the user should be signed out, it uses the following line to do so:
location.href = settings.actions.expireSession + '?returnUrlString=' + currentUrl;
where settings.actions.expireSession is defined as:
expireSession: '#Url.Action("Expire", "Session")'
and the return url string getting into the location.href looks like this:
http://localhost:49574/Report/ReportWithUserIdAndCaseId?userId=84&caseId=173
which is correct, and the entire string assembled together with the url action looks like this:
"/Session/Expire?returnUrlString=http://localhost:49574/Report/ReportWithUserIdAndCaseId?userId=84&caseId=173"
I set up a breakpoint at the point of entry in the relevant method, but what arrives in the string parameter named "returnUrlString" there is missing the "caseId":
http://localhost:49574/?returnUrl=http%3A%2F%2Flocalhost%3A49574%2FReport%2FReportWithUserIdAndCaseId%3FuserId%3D84
consequently, when I enter my username and password to log back in, I get redirected to the following url:
http://localhost:49574/Report/EntrySummaryReportWithPatientIdAndVisitId?userId=84
which fails because it's missing a crucial parameter.
Have I missed anything obvious? Is there something else in the automated background of Dotnet's addressing/redirection system that could be contributing to this mysterious disappearance?
A huge thanks to everyone for reading this, and a gargantuan thanks for contributors!

You need to escape the Url before it is sent to the Session/Expire page.
See this previous question for information on encoding it in Javascript:
Encode URL in JavaScript?
Once you have returnUrlString on your Session Expire page, you should then unescape it and direct the user to it.
The problem is that the Url to the Session/Expire page would be:
"/Session/Expire?returnUrlString=http://localhost:49574/Report/ReportWithUserIdAndCaseId?userId=84&caseId=173"
What the server sees is:
Page: "/Session/Expire?, QueryString ReturnUrlString: returnUrlString=http://localhost:49574/Report/ReportWithUserIdAndCaseId?userId=84, QueryString CaseId: &caseId=173"
It is interpreting your &caseId as part of the /Session/Expire URL. This is why it disappears.

Question mark in script breaks html

I have inserted a block of javascript in then body of a Joomla 2.5 article.
What I want to achieve is to open a default client email engine in order to send some information there.
The code looks like this:
var sendForm = function() {
...
window.open('mailto:admin#admin.com?subject=mailSubject&body=mailBody');
};
What happens actually, when I load the page is that whatever is after the "?" is broken and appears as plain text in the UI.
For example, I have the following stuff in the UI:
?subject=mailSubject&body=mailBody'); }; window.onload = getTotal();
What is wrong? Can you help me to spot the stuff that I am doing it wrong?
Thanks

It seems that this is a Joomla specific problem. I managed to get over it by using the {emailcloak=off}syntax before the actual email address.
Therefore the code looks like this mailto:{emailcloak=off}some#email.com?subject....

You might want to use ? instead of ?, and & instead of &. If you wish, you can refer to the HTML character numbers and names here.
It will not only solve your problem, but also pass the W3C validator.

Replace Values from Url using jQuery

Here i have a URL in Browser Address bar i want to replace path of Address bar using jQuery.
Some try from my side is as below
Consider url as below
http://localhost/catID/10/itemID/20
when i run
history.pushState("CatID", "Title", "21")
it change location bar as
http://localhost/catID/10/itemID/21
but i want result as
http://localhost/catID/21
how can i do this using jQuery

Query not needed. Plain js will do. Just add this code in your function and replace the string with the required arguments. Try it in the console, for an immediate effect ;D
window.location = "http://localhost/catID/10"
If you do not want to reload the page or use # for changing the url, then use window.onpopstate
Modify the URL without reloading the page

Javascript - Check for Hash, Ignore Analytics Code following

We are adding a video to the home page of a site, and want to be able to automatically pop up the video (in a lightbox-style container) whenever the #video tag is present in the URL:
http://www.domain.com#video
The video needs to pop up if a link is clicked internally on the site (ie: <a href="#video">) and also if the hash is present in the URL on page load.
Easy enough to check for the hash in the URL using window.location.hash or when a link with the hash is clicked and fire the associated javascript function. That's working as expected without any issues.
However as this URL will be sent out in emails with Google Analytics code automatically added, the analytics code is appended to the end of the URL:
http://www.domain.com#video?utm_source=...
Because the analytics code will change with each email campaign, I can't do a simple Javascript replace() to ignore the analytics code.
How do I go about checking whether the hash is present in the URL, but ignore anything after a ? if present?

Isn't the proper form of a URL to have the hash at the end after the query parameters? Then, the location.hash variable will work properly and you won't need special code. Your URL should look like this and then you can just directly use location.hash which will be #video:
http://www.domain.com?utm_source=xxx#video
I don't advise this as the solution (I think you ought to get the URLs fixed to be legal), but you can use this code to parse the hash value out of the URL even if it's in the illegal position:
var matches = window.location.href.match(/#(.*?)(\?|$)/);
if (matches) {
var hash = matches[1];
}
This code extracts from the "#" to either end of string or "?" whichever comes first. You can see it run on a bunch of test URLs here: http://jsfiddle.net/jfriend00/HuqL7/.

location.hash.match(/[^?]*/)
Assuming the hash is always first, that should do it.

(This is a literal answer to your question, but there is a huge caveate) Technically, you can just test:
var h = window.location.hash;
var ind = h.indexOf( '?' );
var test = ind <0?h:h.substr(0, ind)
If you want Google Analytics to work, you may have problems #. The rule is that everything after a # is not sent to the server, which means that your Analytics may go out the window. You need to make sure that your hash is added after all of the Google stuff. If it is, then you won't need to worry about testing anything.

Cut string obtained with Javascript inside hyperlink

I made a bookmark that users can add and it sends them to my site capturing the referrer.
Bookmark
My problem is that for some reason the location.href part instead of printing http:// it prints: "http%3A//". I want to remove it and get just the domain.com
I have a similar code that maybe could be useful but I'm having a hard time figuring out how to implement it inside HTML.
// Function to clean url
function cleanURL(url)
{
if(url.match(/http:\/\//))
{
url = url.substring(7);
}
if(url.match(/^www\./))
{
url = url.substring(4);
}
url = "www.chusmix.com/tests/?ref=www." + url;
return url;
}
</script>
Thanks

In most browsers, the referrer is sent as a standard field of the HTTP protocol. This technically isn't the answer to your question, but it would be a cleaner and less conspicuous solution to grab that information server-side.
In PHP, for example, you could write:
$ref = $_SERVER['HTTP_REFERER'];
...and then store that in a text file or a database or what-have-you. I can't really tell what your end purpose is, because clicking a bookmark lacks the continuity of browsing that necessitates referrer information (like the way that moving from a search engine or a competitor's website would). They could be coming from a history of zero, from another page on your site or something unrelated altogether.

Like already stated in my comment:
Be aware that this kind of bookmarking may harm users privacy, so please inform them accordingly.
That being said:
First, please use encodeURIComponent() instead of escape(), since escape() is deprecated since ECMAScript-262 v3.
Second, to get rid of the "http%3A//" do not use location.href, but assemble the location properties host, pathname, search and hash instead:
encodeURIComponent(location.host + location.pathname + location.search + location.hash);
