  12. What happens if you delete the file name? http://bpastudio.csudh.edu/fac/lpress/ The Web server will look for a file with a default name, which is specified by the server administrator. Traditional default names are index.htm, Index.html, default.htm, and default.html.

  13. URL summary http://som.csudh.edu/fac/lpress/shortbio.htm • This request is for a Web (http) server • The server program is running on a computer with the domain name som.csudh.edu • Look in a subdirectory called fac/lpress • If there is a file called shortbio.htm, send it back to the client to be displayed; if not, send an error message back to the client Domain name = the unique name of a computer on the Internet
