Customizing FotoWeb 3.0
2 Customization of FotoWeb
All FotoWeb pages (FWX) are produced based on FotoWeb script templates. The templates are a mix of Htmlcode
and FotoWeb ’tags’, a kind of pseudo-html. By changing the templates you can completely customize the look
and feel and functionality of FotoWeb.
Following the same idea as the scripting technologies, the FotoWeb tags serve as the interface to inner functionality
of FotoWeb. With these tags, we can tell FotoWeb to perform a specific operation and from the same tags we can
retrieve desired information processed by FotoWeb. Before going any further, lets look at some basic scripting
concepts.
2.1 Scripting
The following figures illustrate some basic processing and transmission concepts among Html, Asp and Fwx pages.
. . .
5 – 2 = 3.
Figure 1: A mathematical expression displayed by an Html page.
. . .
Figure 2: A mathematical expression evaluated and displayed by an Asp page.
. . .
5 – 2 = .
Figure 3: A mathematical expression evaluated and displayed by an Fwx page.
All three pages in the above figures will finally display the string ‘5 – 2 = 3.’ in the client’s browser while the actual
pages are designed and processed differently. The Html page must store the final results of the expression in the
page itself. Upon request, this page is transmitted to the client AS IS. The Asp and Fwx pages are utilizing scripting
to allow the final result to be evaluated and added to the page dynamically upon a request. Contents of the raw
page enclosed within the script identifiers (‘’ and ‘’) are replaced with proper Html code before
transmission to the client.
The Asp and Fwx pages are also Html pages with or without special identifiers such as ‘’ (Asp) and
‘’ (Fwx). It is, however, the extension of these pages that inform IIS which module is responsible of
processing and transmitting the page. IIS redirects requests made to Asp pages to the Asp processing module in IIS.
Similarly, FotoWeb handles requests made to Fwx pages. Both modules will then scan their requested pages
looking for the identifiers and process the requests made within them. The identifiers are then removed or replaced
with proper Html code and, finally, the pages are transmitted to the client.
