This "Guest Book" example consists of three main files: GUESTBK.SSI, GUESTFRM.SSI, and SIGNBK.SSI. The GUESTBK.SSI presents the list of guests who have signed in. The GUESTFRM.SSI presents the form to fill out to sign the guest book. When the form is submitted, SIGNBK.SSI is called which actually appends to the guest book file, GUESTBK.TXT and increments the counter in GUESTBK.CNT. SIGNBK.SSI automatically returns to GUESTBK.SSI and shows the new signature.

INDEX.HTM is supplied as a default index file which automatically loads GUESTBK.SSI. If the DefaultIndex for the web server is INDEX.HTM, and someone only specifies the guest book directory without specifying GUESTBK.SSI in the URL, INDEX.HTM will be sent to the client. The client will then automatically get GUESTBK.SSI.

ACCESS.WWW is provided to turn on Server-Side Includes (SSI) in this directory.

GUESTBK.GIF is the graphic that says "Welcome Guests!".
