WEB GET STATISTICS


WEB GET STATISTICS ( pages ; hits ; usage )

Parameter	Type	Description
pages	Text array	Names of the most consulted pages
hits	Longint array	Number of hits for each page
usage	Longint	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 section QR DELETE COLUMN.

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:

 C_TEXT($1)

 C_TEXT(vPages)

 ARRAY TEXT(pages;0)

 ARRAY LONGINT(hits;0)

 C_LONGINT(vUsage)

 

 WEB CACHE STATISTICS(pages;hits;vUsage)

 For($i;1;Size of array(pages))

    \\For each page present in the cache

    vPages:=pages{$i}+"   "+String(hits{$i})+"<br>"

    \\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.
