I tried to download all zip files (school material ebooks) from this site:
<http://bse.depdiknas.go.id/?top=1&mn=1> but have tried several ways without
success.

The problem:
First you choose which ebook to download, and then the site takes you to
Agreement Page where you have to check on Agree check box (Setuju in
Indonesian), after that you are taken to list of zip files to download, each
book contain about 10 zip files. These are the files I need to download.

Question: How to automate download for all zip files from the site in
question.

Thank you for your help.
