While forms can have myriad purposes, in terms of crawling a website using WebCopy they are normally used to authenticate a user.

WebCopy is able to post forms to websites. As well as specifying values for user supplied parameters, the crawl engine will automatically include other parameters present on the original form, such as session tokens or anti-forgery tokens, without you needing to define these yourself.

Forms can be manually defined, or automatically captured. Once you have defined a form, you can test that it works correctly before initiating a website copy.

WebCopy is unable to log into web sites using two-factor authentication (2FA) or multi-factor authentication (MFA).
