Example: web_add_filter
The following example uses web_add_filter to exclude URLs with a path prefix of /Images/Upload. Since the call only applies to the next action function, the filter does not apply to the second call to web_url. All URLs with matching criteria will not be excluded.
// Call to web_add_filter only applies to the next action function
web_add_filter("Action=Exclude", "PathPrefix=/Images/Upload", LAST );
web_url("www.knanas.com", "URL=http://www.knanas.com/", "Resource=0",
"RecContentType=text/html", "Referer=", "Snapshot=t1.inf", "Mode=HTML",
EXTRARES,
"Url=/images/netaction_icon.gif", ENDITEM,
"Url=http://frontpage.knanas.com/Images/Upload/Commerce323.jpg", ENDITEM,
// Will be excluded as it matches the path prefix criteria
"Url=http://frontpage.knanas.com/Images/Upload/Commerce134.gif", ENDITEM,
// Will be excluded as it matches the path prefix criteria
"Url=http://frontpage.knanas.com/Images/Upload/120_eminem-t55.jpg", ENDITEM,
// Will be excluded as it matches the path prefix criteria
"Url=http://frontpage.knanas.com/Images/Upload/153_gavre_sigar.jpg", ENDITEM,
// Will be excluded as it matches the path prefix criteria
"Url=http://realmedia.knanas.com/RealMedia/ads/Creatives/default/empty.gif", ENDITEM,
LAST );
// Out of scope of web_add_filter function
web_url("www.knanas.com", "URL=http://www.knanas.com/", "Resource=0",
"RecContentType=text/html", "Referer=", "Snapshot=t1.inf", "Mode=HTML",
EXTRARES,
"Url=/images/netaction_icon.gif",
ENDITEM,

ENDITEM,
