Autofill windows logon and website username and password fields using Perl?

[shufflestumps]

Edit: The title for this post, or the description of what I am after should have said user login. I am NOT after something that can initially sign me into windows but instead something that will fill in the fields for user access to the browser and to the frequented website (ie: Windows is already accessed) - hope this makes things a bit clearer.

Can anyone please point me in the direction of a script which can be run which will autofill my username and passwords for 1) A Windows login prompt (I need to login using my issued username and password to allow me access to the internet which may or may not be via a proxy server - the reason for this is because after a very brief period of inactivity the session times out and I am repeatedly required to re-enter logon details) and 2) Once logged in and internet access gained a script allowing me again to autofill an issued username and password for a frequented website by running the same or a seperate script

I am fairly new to all forms of scripting including client and server side so I am hoping someone may have some ideas on if this is possible with Perl and if so is there a script that can be downloaded or a link to example content someone may be able to provide.

If it is not possible to fulfill both these requirements with Perl (which I am sure you could somehow) does anyone know of another scripting language which could work for me and again a link?

Thanks all.

Never mind - figured it out myself using Javascript with the page form.
Please mark this thread as solved and apologies for not posting in the Javascript forum however I thought a Perl script run on the local machine may have been an option.
