how can i return msg to label in jsp from servlet.

after clicking the submit button,then call servlet to do something.
afterwards, setSttribute for session and then redirect back to the page.

sometimes, i redirect back to the page after submit form, sometimes, i go to the page by linkage.
how can i distinct the page is entered after submit form or not?
