Need to crawl webpages requiring login details

Vineet

Hello,
i need to crawl certain websites but they require login details to be entered.
I am not able to figure out how to provide my login details in order to get access to my homepage.Is there any operator or any other way to do that??
Please help.!!
Thanks and Regards,
Vineet

Hey,

In the Get-Page operator is an option to activate cookies. Activate it and send your credentials (username and password) to the login page as POST parameter. Usually a web page will store your session in a cookie. Further requests of any Get-Page(s) operator will be handled by the website in the same session (using the stored cookies), thus you are logged in (if your credentials are correct) and can fetch the login-secured websites.

Happy crawling!
