Example: web_remove_auto_filter

The following example uses web_add_auto_filter to exclude URLs with a path prefix of /Images/Upload. The call applies to all subsequent action functions, in this case, the two calls to web_url(). The invocation of web_remove_auto_filter removes the filter from subsequent calls to action functions.

web_add_auto_filter("Action=Exclude",
     "PathPrefix=/Images/Upload", 
     "Id=fid",
     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 );

web_remove_auto_filter("Id=fid", 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,

     // Downloaded because filter has been removed.

     "Url=http://frontpage.knanas.com/Images/Upload/Commerce134.gif",
     ENDITEM,

     // Will be included

     LAST );
