The /atg/endeca/clickthrough/servlet/SearchClickThroughServlet is inserted into the DAF servlet pipeline after the SiteSessionEventTrigger. When a user clicks a link to view a search result, SearchClickThroughServlet reads the click-through ID from the request URL and looks up the record in the SearchRequestCache. If it finds the record, it triggers a SearchClickThroughMessage JMS event, which includes the search ID, the record ID, and data about the search request.
To configure this servlet, set the following properties:
enabled
Iftrue, the servlet processes the request. Default isfalse.
searchClickIdQueryArgs
An array of the query arguments to read to find the click-through ID for a viewed item. One of the values in this array must match the name of the output parameter set byGetClickThroughId. Default issearchClickId.
Limiting the Pages to Examine
By default, this servlet examines all URLs to look for click-through IDs. This process can be inefficient, because only product detail pages will typically have these IDs. Therefore SearchClickThroughServlet has a clickThroughPages property that you can use to limit the pages to examine. This property is an array of URLs, which can include asterisk (*) characters as wildcards. If clickThroughPages is not null, SearchClickThroughServlet examine only the URLs that match one of the clickThroughPages entries. For example, you could set clickThroughPages to:
clickThroughPages=\
/*/*/productDetail.jsp,\
/*/*/productDetailWithPicker.jsp,\
/*/*/giftCertificateProduct.jsp
