How would I go about capturing the existing URL in someone's URL: bar and adding a few elements to it on a link the user would click?
Example: I have an ability for my users to sort, which brings up the same page, but with different variables each time a particular type of link is selected. I want to be able to create a link that will capture the exisiting configuration they have in their browser, and add on a limit point.
I'm thinking I would use some sort of HTTP var, but not sure how exactly..
