Usage Notes

Site Retriever abides by the Robots Exclusion Protocol so some pages may not be downloaded if the webmaster has chosen to block them from softbot access.

Site Retriever only downloads pages that are apparently in the same branch as the root URL specified on the command line. For example, if


http://croftsoft.com:8080/people/david/

were specified on the command line, only pages that match the following criteria would be downloaded:

Your e-mail address is provided on the command-line so that webmasters may contact you if they have problems or concerns with your use of Site Retriever on their site. Your e-mail address is passed to the web server with each file request as part of the standard request header.
