I have 3 web sites where there are many catalogs I'd like to get extracted:
- data in a sql file
- images in a local folder

There will be also restricted areas where it is needed userid and password (that I have).

What I need is an application that get inside those pages and get all needed info extracted (e.g: product code, name, availability, etc). I'll need to change the passwords every 3 months, so I need instructions on how to change password on the application or it could be better to have a panel where to set the passwords.

I need it in 1 week.
