Will the RouteFinder log all visited URLs to file and send the log to a specified e-mail address? Can it deny access to some URLs (example: a URL which contains the word 'sex'), a simple URL filtering based on keywords?

1) The logs are stored in the RouteFinder and it does not email the http access log. An admin person must ssh into the box and get the files.

2) The RouteFinder allows you to create a custom filter list of URLs that you do not want your users to access, but it is based on URLs only. It is not based on the content of the web pages.
