To access a webpage multiple times

I have a website : where I have to input data into multiple text-bars
multiple number of times and there is a submit data button which I use
after the data have been given … After the submit button is clicked the
webpage is directed to another page and I have to collect data from that
page where there is a link for a ascii file that I have to download .

As I said this process have to be done multiple times :

The webpage is : http://omniweb.gsfc.nasa.gov/vitmo/iri_vitmo.html

I have to access this webpage multiple times and collect the data that
the webpage gives when the submit button is clicked … If a script in
RUBY can do this ,… It will be great …
