I'm writing a module that displays graphs based on a selection of arguments (an array with items to display, a daterange and some other stuff). This results in a long and ugly url.
Is there a way to get the arguments to the page with the graphs without putting everything in the url for that page? I'm looking for something that can keep temporary variables with a short reference that I can pass in the url, but haven't been able to find anything.
I'm using Drupal 7.
