WEB GET STATISTICS

WEB GET STATISTICS ( pages ; hits ; usage )

Parameter	Type		Description
pages	Text array	←	Names of the most consulted pages
hits	Array integer	←	Number of hits for each page
usage	Integer	←	Percentage of the cache used

Description

The WEB GET STATISTICS command lets you get information about the most consulted pages loaded in the Web server’s cache. Consequently, these statistics only concern static pages, GIF pictures, JPEG pictures <100 KB and style sheets (.css).

Note: For more information about setting the 4D Web server’s cache, refer to the Web Server Settings section.

The command fills the pages Text array with the names of the most consulted pages. The hits Longint array receives the number of “hits” for each page. The usage parameter receives the percentage of the Web cache used by each page.

Example

Let’s assume that you want to generate a semi-dynamic page that displays the statistics of the Web cache. For this, in a static HTML page named “stats.shtm” (pages suffixed .shtm are automatically parsed by the Web server), you place the tag <!––#4DSCRIPT/STATS––> as well as references to the vPages and vUsage variables, for example:

<html>
<head><title>4D Web Stats</title></head>
<!--#4DSCRIPT/STATS-->
<body>
<strong>Percentage of cache used: </strong>
<!--#4DTEXT vUsage-->
<hr>
<strong>Pages consulted most often: </strong>
<!--#4DHTML vPages-->
</body>
</html>

In the project method STATS, you write the following code:

 var $1 : Text
 var vPages : Text
 ARRAY TEXT(pages;0)
 ARRAY LONGINT(hits;0)
 var vUsage : Integer
 
 WEB GET STATISTICS(pages;hits;vUsage)
 For($i;1;Size of array(pages))
    \\For each page present in the cache
    vPages:=pages{$i}+"   "+String(hits{$i})+"
"
    \\Insert the name of the page and the HTML code
 End for

You can send the "stats.shtm" page using a URL link or using the WEB SEND FILE command.
