You mean you have a single-paged application and rewrite the
underlying page asynchronously? How do you deal with needing to load
different Javascript files per page? I guess you could simply load all
the JS files all your pages would ever need, but I assume you do
something a little more sophisticated.

The way you did it was with what I call a "one shot cookie". A project I
worked on I did a solution where sessionStorage was used to keep a token
and a cookie was set via javascript and thus sent along with the request
to the server which then tells the browser to delete the cookie in the
reply.
If the token needs updating then the server can send a "one shot cookie"
to the browser, the javascript will then apply the needed changes to
generate a new token (maybe a new salt or nonce is given) and then
delete the cookie.
Also, this form of cookie use does not fall under the "cookie law" in
Europe AFAIK as it's part of a login mechanism so no need to show those
annoying "this site/page uses cookies" box or warning.
Using sessionStorage, and cookies to pass info to/from the server is my
new preferred way as you can control how often the cookies are sent and
to what part of the site.
The solution is not as elegant as I'd like it though. One issue is you
can't set the timeout for a cookie (sent from the server) to 0 or 1 sec
or similar as the browser could delete the cookie before your javascript
can get the data from it.
In the other direction the issue is reliably deleting the cookie after
it has been sent (sometimes one can use POST requests and avoid this
part, but that may not always be practical).
Looking at
http://stackoverflow.com/questions/26556749/binding-tab-specific-data-to-an-http-get-request
the solution you ended up with is very similar to what I ended up doing,
I'm not aware of any better way to do this (yet).

Roger.
