Re: [R] URL Scan

The site does not require a login/password. Another way to access the first site would be to go to the second site, click Connecticut, click Canterbury, CT, enter the online database, click search under Query by Location with nothing in the search fields, and click the first property. Viewing the frame source on this page redirects to the second site.

Also, could you direct me to or give me some instructions on scanning from sites that do require a login/password? Thanks.
