using javascript as a way to store session variables

[seospace]

Can someone explain to me if the following is possible and if so is it a recommended practice? The issue is whether the option of using javascript as a way to store session variables (versus a URL) for a website. The ultimate goal is to have ONE URL for every page...and only one URL. The search variables that are necessary for navigating the site and for displaying content are to be stored "behind the scenes".

Example:

Assume that the following 2 URLs link to the same page:

1. [siteexample.com...]

2.
[siteexample.com...]

The links are very similar. The difference is link 2 contains query
string parameters (?searchId=100006648&offset=0) that are needed for
human user functionality.

The goal is to always present the same link for the same content for a robot user while not compromising the human user's experience.

POTENTIAL SOLUTION (Will this work?)

Potentially this problem can be solved by statically writing link 1 into the HTML of the page. This will allow robot users to follow link 1 to the page without any problems.

A human user that clicks on link 1 in their browser will have the link rewritten using Javascript, then followed. This satisfies the human user functionality requirements. In theory, robots are not able to "find" this link and follow it.

QUESTIONS

Which robots have built-in Javascript engines, if any?

If a robot does have a Javascript engine then how much processing will it typically perform to determine a link? Is the engine sophisticated enough to read constants, perform calculations (such as string concatenations), and run functions?

Which robots accept and use cookies, if any?

The problem I see is that sites are likely to link to you including the searchid. Search engines following these links see it as duplicate content.

As far as I know search engines dont do anything smart with the javascript but may parse it for link like text, external js is less likely to be parsed, also dont store url as single literal. I dont know of them excepting cookies, but seems easy thing for them to do.
