Usually when I do this for an upload, etc... it means that a user just did something that resulted in an row being created in the db. I usually keep a boolean field in the table for processing. Then when I load the next page I can just query that value right before I choose the template to see if it's done processing, if it's done show the result page, if not show the processing page and send the id of that process along so I can query it using ajax every so often to see if it's done then load the results page.
Progress is a little harder. If it's a large file I would use something like swfupload to show the user real time progress on the page before loading the next page. If there is a better way to do these things, I'd love to know too.
