public class SearchClickThroughServlet
extends InsertableServletImpl

This class is used to create components for inserting into servlet pipeline to get search click identifier (query id and document id) from the request. After getting searchClickId value and parsing it into queryId and documentId values it perform lookup for document and cacheElement objects in cache/history components. In case of all objects where found, we can treat such activity as a successful click-through action and fire SearchClickThroughMessage JMS event with required information.

Component is implemented to proceed only with configured list of page URLs and configured request parameter names.

Enabled property controls whether servlet should process request or transfer its execution to the next one in a chain. SearchClickIdQueryArgs property contains query parameter names which we will look for searchClickId value in request. ClickThroughPages property controls the list of pages which will be processed by servlet and we will look for searchClickIdQueryArgs for them. Wildcard characters can be used. If this property is null, then searchClickIdQueryArgs are looked for all pages.

The use of the clickThroughPages configuration is shown in the following example:

 clickThroughPages=/*/*/productDetailWithPicker.jsp,/*/*/productDetail.jsp,/*/*/giftCertificateProduct.jsp,/*/facet/facetGlossary.jsp
