Need to fill password in with perl on Javascript?

[jdlev]

I've got 2 routers I want to monitor (basically to see if a website goes down). If the website goes down, I want to navigate into the router, and reboot it (which fixes the problem 75% of the time).

I've got a javascript form on the router webpage that requests a password. What's the best way to do this automatically using Perl?

Also have another router site that requests a username & password, but it looks like it comes from a windows prompt. How can I use Perl to automatically enter a username & password into that field?

TIA!
